Good quality time spent with the physician. She answered all my questions and we worked together on a plan going forward. Very good visit.
I've left my doctor of a decade because of good previous care from Dr. Maria Juarez-Reyes
Dr. Juarez-Reyes consistently demonstrates appropriate concern in a friendly, warm manner. Always explains condition and plan to address any problems.
Dr. Juarez-Reyes is always superb with her patient care & communication.
I have recommended to friends and colleagues
Dr Juarez-Reyes is the best! She is compassionate, explains things very well, very knowledgeable, very kind and pleasant. I can't say enough good things about my experience with her.
I think there we about 10 of us in the group. These were collaborative visits. The MD running them was careful to pay attention to each participant.
This visit was very nice- thorough with enough time to cover all issues and questions and conversation about referrals. Very much appreciated for a yearly visit.
I felt Dr. Juarez-Reyes was fabulous, and was glad I persevered through the difficult process to get an appointment, and waiting months to see her.
She is excellent! Wish every doctor (and human) was a empathetic and patient as she is. The class and lessons she provided have been super beneficial.
Doctor Maria is my super doctor, I depend very much on her advice & opinion.
Dr. Juarez-Reyes is always thorough. She has my trust
dr Reyes is the very best. professional and caring. I am very grateful.
the dr. ws concerned, insightful, compassionate and thoughtful.
I could not have had a better experience or a more concerned, thoughtful, practicable and caring primary care pysician
Dr Maria is absolutely lovely in her medical care for me. I am most appreciative to have her as my doctor. Thank you!
dr Reyes is very professional and smart!
Excellent
Dr. did not have enough time to spend with me. She was doing her best to help me, but she had other patients and although I tried to schedule a long appointment, her time with me was very limited.
Dr Juarez Reyes is awesome, seems to genuinely care about your wellness and is supportive in her communication.
Dr. Reyes is excellent. She listens and communicates well. Great treatment & follow through.
Dr. Juarez-Reyes is amazing. Showed concern and let me know she was there to help; very knowledgeable about my problem and connected me to/reached out to specialists that could help me.
Care provider did not seem to have taken my concerns seriously when suggesting a treatment. I had to go an urgent care center the very next day for excruciating pain - this could have been avoided if this Doctor had done the relevant exams and taken my condition more seriously
dr Juarez-Reyes is excelent.
Dr. J-R is an excellent communicator, diagnostician & listener. She is easy to understand and offers practical solutions.
Dr. Juarez-Reyes is wonderful.
Excellent experience
The visit with Dr. Maria was very good, where things failed and still failing is follow up. The insurance needed pre-authorization from the doctor for the prescription. I sent an email from MyHealth, no answer, I called the Clinic and they took a detailed message for Dr Maria and no message back. The pharmacist tried to get authorization back and failed as well. So jhere we are with a prescription that can not be filled and not sure how to get communication or attention to this matter.
I LOVE Dr. Juarez-Reyes. She is always sopatient and willing to listen. She is very positive and encouraging. She truly shows genuine interest in taking care of her patients. I appreciate she takes care my health with a wholistic approach.
Dr. Maria Juarez-Reyes is simply an outstanding doctor. She is compassionate and shows that I am important to her, that my issues matter.
Best dr. ever had.
Dr. Juarez-Reyes was great- I have a difficult, multisystem, poorly-characterized illness (EDS/MCAS/ME/CFS/Lyme/Fibro/adult PANS/autoimmune encephalitis), and Dr. Juarez-Reyes took the time to listen to my entire history, and expressed interest, concern, and compassion. I have seen many MDs over the years who have stubbornly refused to believe there was anything wrong with me outside a psychiatric condition. Dr. Juarez-Reyes not only had some understanding of my pooly-characterized condition, she was willing to listen, learn, and even offer functional medicine perspectives, when a clinical diagnosis has to be used if diagnostic testing is not yet possible.
Dr. Maria Juarez-Reyes is very thorough, professional, and always takes the time needed to address whatever concerns need to be covered. My husband met her on this visit and he was very impressed with her. Also, getting in to see her is not as difficult as it can be with specialists.
Dr Reyes is an excellent internist. The communications between us is very good.I feel she genuinely cares for my health.
Best doctor: Dr. Juarez-Reyes.
Absolutely an excellent doctor, woman and care person. I am blessed to have her guidance and care. thank you
Good.
Dr. Juarez-Reyes is always through. Even when she was pressed for time, I did not feel that our visit was rushed. She is one of my favorite doctors.
She arrived on time and apologized for any delay. She listened well and collected background information. She diagnosed the problem, but since she is not a specialist in this area, she took a photo to forward to a specialist. She prescribed medication, gave clear instructions and told me when she expected she would hear from the specialist. Sooner than expected, the specialist informed her he agreed with the diagnosis and treatment plan; she passed that information to me. The medication seems to be working as hoped.
Always a positive and helpful experience
Dr. Juarez-Reyes is one-of-a-kind. She is knowledgeable and informs me well.
I feel particularly fortunate to have Dr. Maria caring for me. She is thorough, clear and kind.
I had to ask about side effects of a new medication, Losartan and what to do if I had problems. She listens well but could do better with sign posting and explaining the "Why" of things.
Care provider excellent as always.
Dr. Juarez-Reyes is excellent with her knowledge, care and concern.
My doctor always listen my problem/symptoms. I already referred to my acquaintances.
Dr. Maria Juarez-Reyes was very helpful as always. Her kind and caring manner as well as her explanations really help me in my healing.
Dr. Juarez-Reyes is genuinely concerned about any conditions or problems that I may be having and I am always included in all decisions regarding my treatment. I feel very lucky to have found such a wonderful and competent care provider.
Excellent. Last time I had the same life threatening condition, your appointment line sent me to Express Care where I only saw a PA July 3rd and he did not recognize what the infection was, made me wait 2 days for antibiotics and by then it had doubled in size. That's why I insisted on seeing my regular doctor who has treated these issues before and understood the seriousness of being seen and treated right away. She is terrific!
I was treated really well so I felt comfortable for my appointment.
dr.reyes is awesome! I was referred to her from a friend and I also referred those in my family to her too..when people ask for a pcp I let them know about Stanford portola clinic
I feel Dr. Juarez-Reyes spends too much time typing in information & not enough getting to know the patients whole situation. I feel doctors are becoming data input technicians.
The doctor was very enthusiastic and helpful. She spent over an hour with me, reviewing my medical history and discussing my current medical needs and options. She is strongly supportive of integrative medicine, which I greatly appreciate, and is confident that my medical issues can not only be treated but resolved. She had already contacted a specialist to see me before I'd even gotten to my office after the appointment. It was a fully positive experience! The only thing I'm unsure of is when I need to return to see her in the midst of going to various referred specialists.
Dr. Juarez-Reyes is very personable, likeable, and reassuring. She explains issues and options very well.
Dr Maria is absolutely the most wonderful, caring and upbeat doctor I have ever encountered. She has integrity, kindness, competancy and everything I could ever ask for in my doctor. Thank you!
I really liked my visit with Stanford. I received some great care.
Dr. Reyes is an excellent provider - I'm healthy but she still spent sufficient time with me discussing future issues.
Dr. Juarez-Reyes is the best all-around primary care doctor I have had, and I have had many.
Exceptional time provided!
good experience with the physician.
Dr. Juarez-Reyes always provides excellent service. In all my visits, she is very efficient and able to address all my concerns.
It's always a struggle to have a long enough time with my doctor. The clinic seems always to run late, yet strives to catch up by urging the doctor to cut off the conversation with a knock on the door. Dr. Juarez-Reyes is careful, responsive and helpful.
excellently good
Dr. Juarez-Reyes is such a wonderful doctor. This was my first visit with her, and she was able to help me feel at ease, connected with me, helped motivate me around my health, and gave me a good sense of how we would proceed moving forward. I felt extremely well cared for.
I think IR Juarez-Reyes is a skilled professional who is exceptional!
Dr. Juarez-Reyes was FANTASTIC! I could not have had a better experience.
Dr. Juarez-Reyes is very attentive, personal and puts a lot of care for her patients although I was late (10 mins.) she made time for me and did not rush through my appt. she's terrific.
A++.
I love Dr. Juarez Reyes! She is very thorough and always puts me at ease with her kindness and friendliness. She has great warmth and energy at every visit.
Dr. Juarez-Reyes was outstanding... I am very glad I made the switch to her - she was clear and attentive - listened carefully to all my questions and gave me solid, thoughtful answers.
Dr.Juarez-Reyes is a true caring professional. We turned to her while Dr.Tang has been on maternity leave. Her responsiveness and decisions regarding my care is impressive. I don't feel like a number. She asks for and considers my responses. I am know I am in good hands.
Dr. Juarez Reyes makes you want to follow her advice and she is very encouraging
Care Provider is excellent.
This is the best doctor I have ever seen in my life. The level of care was remarkable. I really liked the doctor's ability to view and discuss my medical history on the spot. The level of detail into my family history was good. The amount of time spent with me in general exceeded my expectations. I really feel that for the first time in my life I have a greatest chance of being the most healthy person I can be with this doctor on my side. Wish I found this doctor sooner.
I have already recommended Dr.Juarez-Reyes to a friend looking for a doctor.
Best experience ever. She's fantastic. I already recommended her to two friends/family members.
Dr. Juarez-Reyes is a gem. I consider myself so fortunate to be able to be her patient and to have her managing my care. Dr. Juarez-Reyes is warm and a great listener.
Dr Reyes is excellent. Understanding, professional & understands my philosophy of prevention.
the dr. always does an excellent job when she see me.i have great confidence in her.she is also concern with other needs of mine that i would have not thought to mention to her.
this appointment was to establish care. unbelievably thorough and thoughtful review of my medical history and guidance for future care. impressed!
My provider was fantastic. She listened, was personable, and took the time to explain her thought process to me.
She is a very good doctor, and always pays attention about my concerns and I received good information when I have questions.
Dr. Juarez-Reyes is the best primary care physician that I've ever had. I have not been extremely happy with Stanford Health Care, but Dr. Juarez-Reyes will keep me here because I don't want to lose her as my primary care physician.
I totally trust and appreciate Mari Juarez Thank you
very impressed with the Doctor. very knowledgable, genuine, caring and concerned. she was recommended to me by someone else and I would not hesitate to recommend her on
I had a lot of questions and appreciate the Dr. to allow time to answer them. I didn't feel rushed.
My visits with this physician have not been good experiences for a number of reasons. I have not felt listened to as she frequently interrupts and has even reprimanded me when I attempt to advocate for myself. It has been apparent that she frequently interprets my questions as challenges, and has, in fact stated that. Recently I left a message that was deemed "urgent", regarding my concern about URI, however did not receive a call back. When I called again the following day I was told that the physician did receive my message....and was informed that I needed to schedule another appointment with her, although I had just been seen by her the day before. In the 2 years I have been a patient of this physician, she has never contacted me personally when I called with concerns or questions. Needless to say, I do not wish to continue with this physician, nor will I recommend her to others.
Very happy with the level of care I am receiving from Dr. Maria Juarez-Reyes.
Excellent, intelligent care!
Dr Juarez-Reyes bases her decisions on the evidence presented. I have high confidence in her scientific judgement.
like her politeness, respect for patient, and thoroughness. yes, i did and will recommend the dr.
all good experience
Dr. Juarez-Reyes is excellent. She always knows which medication would address my problem.
Excellent doctor, great in researching my problem, ordering ... plan of treatment good listener show concern for my medical problems, good personality.
I do not feel that she really listens to me. She lectures and shames me. I don't feel part of the therapeutic process.
this physician was the best i have ever experienced took the time to get to know me.
very nice
Dr. Juarez-Reyes is one of the best Stanford doctors I have met with. Top notch.
I have recommended Stanford to numerous people and I have recommended Dr. Juarez-Reyes to two people specifically and they now see her as their PCP.
I feel I have a good rapport with my caregiver & we can discuss any health concerns - that is very reassuring!
I am new to this clinic as my long time Physician is no longer available; I was a bit cynical as my experience with specialists recently has been less than satisfactory. My current Physician, the staff, and the facility at Portola are stunningly good.
wish each visit wasn't so hurried. I had another concern but she only had to go over one issue. i truly appreciate her care and expertise, but wish visits weren't so rushed. There is always a wait (at almost all SHC doctor visits and then they rush). I write everything down ahead of time so that I can address it with her immediately and tell her everything she needs to know about my issue, since I know that it will help her, but it feels wrong that everything needs to be rushed. I walked out feeling like I still had questions, so I did send an email. I received a reply the next day, it was not an answer just an acknowledgment. Odd) I never experienced that when I went to Palo Alto Medical (for 14 years prior joining SHC). I wish I could afford to go back to PAMF. the doctors and nurses weren't so rushed. I do really like Dr Juarez-Reyes. She tries to give you her all. And she's good. She just doesn't have time she probably wished she had with a patient. Every visit doesn't require time, but some times they do. When they do, they should get it. Everyone is trying, it's just is the way things are set up, the way things are running ... it needs tweaking.
What a wonderful doctor! Loved her from the start! Dr. Juarez-Reyes made me feel welcome and supported from the moment she walked into the exam room, she is thorough, and you know she will manage your care with expertise and knowledge. You know that she is listening and that she will take care of you, all while warming you with her smile.
Doctor, nurse and staff are amazing.
Very caring, informative. Very high-energy, which can be positive or negative depending on patient. Overall, good experience.
Appropriate and helpful experience
Dr. Juarez-Reyes is deeply compassionate and is an outstanding physician.
excellent experience
Everything was terrific with Dr. Juarez-Reyes. I'm very happy I got her!
Excellent care!
The doctor was extremely effective understanding my injury. I was very comfortable with his treatment.
Loved her!!!
Dr. Juarez-Reyes, with whom this was my first visit, spent a lot of time with me trying to establish reasons for my inability to gain weight. She was thorough and attentive, even though the "eat more calories" suggestions is ineffective for me.
best doctor I have ever had
excellent doctor and care assistant. Am thrilled to have Maria as my doctor
First - rate care!
Dr. Juarez-Reyes arrange for an appointment with dermatology in a very short time.
Fantastic doc... best ever.
very good
Dr. Juarez-Reyes is extremely knowledgeable and personable. She shares info & seeks my input. An excellent provider, I recruited my husband & speak highly of her & all Stanford providers to family & friends.
too much time in front of computer
Loved, loved her.
My doctor is a wonderful person, I'm very happy to have her as my doctor. She always answer all my questions the way I understand. I feel so comfortable with Doctor Reyes that I don 't know what I'm going to do if I have to change doctor
Dr. Maria Juarez-Reyes has been fantastic!
My physician was very helpful and listened and addressed my concerns. I would have no problem referring her to a friend.
Dr. Juarez-Reyes is hands-down one of the best primary care physicians I have seen. She is not only kind and personable but also is clearly very knowledgeable and can relate that knowledge to patients easily. Throughout the entire visit, Dr. Juarez-Reyes was very patient and attentive, and it was very apparent that she truly cares about her patients and their overall well-being down to every last detail.
I have already recommended Dr. Juarez-Reyes to six friends - I know of two who have already been to see her.
I feel very fortunate to have found Dr. Maria Reyes-Juarez as my new PRIMARY HEALTH CARE PROVIDER. Her insistence on me taking my meds was instrumental in my recovery. I take meds a bit reluctantly.
I'm super impress with Dr Juarez.. she is human.. my last ten YEARS I have been looking for a Dr like her.. I'm bless!!
Dr. Juarez is the best. She is very understanding and compassionate about my worries and concerns and takes the time to answer all my questions.
Dr. Juarez-Reyes is warm, caring, attentive. She has a wonderful presence. She possesses a holistic perspective on health. She also provides detailed information on particular health issues.
Other than the fact that I am still ill--experience was excellent
Maria is a fantastic and caring physician! Give this doctor a raise.
Dr. Juarez is a great doctor and really cares for the well-being of her patients
Dr. Juarez-Reyes is an outstanding Doctor. You can tell she genuinely cares about her patients.
The doctor was very cordial, friendly and very professional
she is great. i just wish she was briefed or reviewed some sort of documentation to remind her of the reason i am coming back for multiple follow-ups. she mentions the general reason but i have to remind her the placement and nuances.
I did find the follow up notes a little difficult to understand (re: exactly what I was supposed to do next)
Dr. Juarez-Reyes was very rushed throughout the visit, only spending 7-8 minutes total with me. Her exam was rushed, she barely let me talk and explain my symptoms. She also cut me off numerous times when explaining what medications I was taking. When I told her I had taken 20-30 mg of Prednisone to help with my sore throat because I was out of town with my family and feeling pretty terrible, she barely let me finish and scolded me for doing this. I expressed that I understood this and she asked very rudely, "What is it that you do exactly?" And I told her that I am a critical care nurse. She was very rude and condescending.
Maria is amazing! Super friendly and helpful!
She seemed a little more hurried than usual.
Switching to a new doctor is never easy, but when I met the doctor I was reassured and she went over everything in detail and with attention to my concerns. I very much appreciated her attitude and care.
Dr. Juarez-Reyes, in addition to being an excellent physician, is also a wonderfully warm and caring person.
great person and professional
I really like her and have confidence in her abilities. But, I felt like I was "on the clock." particularly for a first appointment. There was no time for a pap smear, no physical examination except for what I asked about (knee) and vitals. I am accustomed to a far more thorough physical exam and would have expected that here, especially as it was our first meeting.
I would have appreciated more concern and information about my colon's diverticulosis. Her exclamations of "there's so many!" triggered my own worry about what it could mean but she did not pursue it any further. I guess i am to assume there's nothing to be concerned about; however information about whether there is something i could do to reduce the diverticulosis, etc. would have been appreciated. Still, if the doctor is not showing worry, i will not concern myself about it.
Dr. Juarez-Reyes was excellent. She communicated well with my 90 year old mother and addressed a myriad of concerns in our first visit. She was very caring.
My reasons for transferring all my medical records for appts., and specialists at Stanford has never been questioned. The BEST, decision!!
I would definitely recommend my doctor to others.
Dr Juarez-Reyes was very friendly, courteous and caring about my condition. She listened well to the occurs cr of my situation and gave great care in giving me next steps in my treatment with urgency and thoughtfulness. I have full confidence in her and value her care as a doctor. I would absolutely recommend her to others!
Dr. Juarez-Reyes was absolutely wonderful to interact with.
You guys are the best! I have never had an issue with Dr Reyes or anyone in that clinic
excellent physician. very professional and knowledgeable
excelent!!
dr Juarez Reyes was excellent. thorough and interested. spent good amount of time and took sincere interest with good advice
Dr. Guadalupe Juarez-Reyes was very thorough, and fully explained my health issues. Very impressed that she covered the different issues I have and showed the connections in a "wholistic" way, in the interest of pinpointing the key concerns.
This was an initial visit to initiate care & I will not go back. Dr. Juarez-Reyes did not read by medical history at all and spent much of visit advising about minor issues w/out having a sense of my medical history/surgeries/health concerns. She was also abrupt, contradicted advice that I have received from specialists (at Stanford) w/a rude quip ("Well, that is not true, but clearly you have a relationship w/this other doctor.") Left me very unsettled. Primary care doctors should read histories before doling advice!
Dr. Juarez-Reyes was very thorough and spent a lot of time with me.
Although this was my first time meeting with this care provider, she made me feel comfortable and confident in her care. I greatly appreciated the time she took to thoroughly review my records and understand my medical history. She was personable, understanding, non-judgmental and knowledgable. I will definitely follow up!
Dr. Juarez-Reyes is fantastic. She was authentic, present and caring.
Dr. Juarez-Reyes is the best primary care doctor I've ever had. She shows real concern for my overall health, not just isolated symptoms, and provides thoughtful advice about healthy living. She is efficient but doesn't rush through the appointment. She clearly keeps up to date on current medical research and recommendations for women's healthcare. She puts you at ease as a patient.
I feel like I am so lucky to have Stanford Health Care. I live in Petaluma and travel to Stanford because I want the best care possible and everyone there is so professional and great!
I was very impressed with the skills and professionalism of Dr. Juarez-Reyes.
very good doctor listened to my problem discussed what to do was reassuring
This was my initial (first) appointment with Dr. Juarez-Reyes. Spent an hour with me! I felt very heard. I liked her thoroughness and was pleased to see that she moved her computer screen with my medical history, so that I could see what she was looking at. I felt like I was participating in my care and not that she was only looking at the screen. She was really relating to me - very important in a Dr. In summary, I was very happy with the appointment and also with the follow-up info she sent me on My Health.
All was very good, thanks.
All very good, absolutely no problems and have expressed my positive impressions to family & friends.
It was my first time to see the doctor. I need more time to give any correct evaluation.
Very appreciative of her holistic approach in wanting total health for my body and mind. She was generous with her time with me and gracious in addressing all my questions.
D. Reyes is always friendly, professional, thorough, and informative.
Fine doctor & clinic visit - thanks.
This was only my first visit with Dr. Juarez-Reyes, and my inital impression is positive.
Already recommended this primary dr.
Dr. Juarez-Reyes is our outstanding clinician - one of the best I have encountered.
Very impressed with her professionalism. I underestimated her knowledge on one health subject and now I stand corrected after reading recommendations by her.
Best doctor I have met! I am very happy to see her!!
I would like to see more personal balance between the computer use during the visit.
She really listened to my complaints and was understanding. And she made reasonable goals for my weight loss plan.
I drive from Stockton, CA just to see my doctor, she is great and the entire office is great!
Feedback from tests was provided online which was good for the information being provided and allowed me to have a copy with the data.
I've already recommended Dr. Reyes to several friends.
