Dr. Morioka is remarkable - ... my best experience with a physician. The best.
The doctor's care was excellent. I needed just a routine physical, but she spent a lot of time with me discussing concerns I had and writing out an extensive and helpful list of recommendations. The doctor was not my normal provider, so this was the first time I had seen her. This visit was the best experience I have had at Stanford Health Care in the three years I have been going there.

This is return visit for my medical leave. Dr. Morioka carefully examined me and she's pleased with my health recovery progress. She's patiently listen to my concerns and encouraged me keeping good work. She also advised me on continuing health improvement and area to pay attention to.
I would say Dr Morioka is one of the best doctors I have ever had the pleasure of working with on my health . She has an excellent bedside manner, is thorough, takes time to discuss any matter of importance, is truly concerned about a patient's well-being - not only with specific health items but any other matters that may be impacting one's health - e.g. I have an elderly parent - how is that impacting me and how am I taking care of myself? I feel very fortunate to have her as my doctor.

Very good dr. -
Dr. Morioka, is one of the best doctors Stanford has in my opinion. She always makes me feel like I'm her only patient.

Perfect visit. No concerns or changes.
I liked receiving written instructions

The appointment was not at all rushed.
I have had very good care form my PCP for many years.
My care giver has been my primary care physician for more than 25 years. I have complete confidence in her and her relationship to me. She always listens to my concerns, Stanford and I are both blessed to have her on our team.
This care provider, Doctor, has even my Primary Care Physician for 22 years. I have complete confidence in her and have had excellent care and attention on every visit.
I truly trust Dr. Morioko-Douglas, Dr. Sklarin and Dr.Tran. I had quite a few medical procedures and all were handled well. I especially liked how all three doctors spoke to one another via email about medical procedure and biopsy.
I have been a patient of Dr. Morioka for many years. She has always gone over and beyond providing medical care.
Dr. Morioka is fantastic!
Dr. Morioka Douglass is a wonderful person and was concerned and helpful.
Care provider seemed eager to move on to next patient, during my appointment with care provider. I spent only a short amount of time with care provider (maybe 10 min or so), still had questions for care provider, but care provider was literally already standing at the door, obviously ready to leave, while I still had questions to ask. Answers that care provider attempted to provide me seemed rushed, as if care provider only wanted to provide them so care provider could leave to see next patient. Was not overall very happy with the visit and the care I was provided.
She's been my doc for over 30 years. Smart and caring. Helps me navigate the system.
Nancy is not my PCP but she was absolutely fantastic! Thorough, fast and covered even more than what I actually went in to see her about.
Care provider was thorough and competent. She made sure that we covered all of the necessary health concerns.
Dr. Morioka is excellent. She provided a clear treatment plan, documented it and followed up. I appreciated that she had a same day appointment available for my urgent need.

My doctor, Nancy Morioka-Douglas is beyond the Very Good you have as a choice. She has been my physician for years and has taken time with my situation, remembers small details about my life, gives great advice. I am so fortunate to have her.
Dr. Morioka is an excellent MD
I have been a patient of Dr. Morioka's for many years now (17?). She feels like a friend when she enters the exam room, always asks me about the parts of my life that are important to me, and takes all the time I need. My confidence in her is such that I will follow through on things I would prefer not to do (e.g. colonoscopy) simply upon her recommendation. She is an incredible listener, and she allows me to be an active partner in my health care. You have to make it so that she can NEVER retire, OK? (Geez, I wish that was a reasonable request!)
Have been a patient with Dr. Morioka Douglas for 20 years, and think she is outstanding.
Dr. Morioka-Douglas is a great doctor who cares about her patient.
Dr. Nancy Morioka-Douglas has been my Primary Doctor for a long time and I get the best treatment. She takes time in explaining about my problem and condition with pictures and other devices.

Dr. Morioka is an exceptional doctor!!
Best GP I have ever had!
Dr. Morioka Douglas is an excellent doctor who is concern with my health and takes time to answer all my questions
I think that doctor should ahve more time with patient. It is very difficult understand what is going on with the patient for 15 min.!
Dr. Morioka actually used some of her lunch time and asked me to come in earlier than my scheduled appointment so we would have enough time to talk. I consider that going way above and beyond the norm. I have been going to Dr. Morioka for over 20 years and hope I die before she retires!
Dr Morioka is the best!
NMD ia a wonderful PCP - there should be more like her.
Dr. Moriaka Douglas is one of the most caring doctors I have ever met.

I have and will continue to reccomend her as a doctor for my friends and family
Dr. Morioka-Douglas squeezed me into her busy day and spent a lot of time with me. She is the best!
She's a treasure.
I LOVE LOVE LOVE Dr. Moriaka- Douglas. She really listens, gives me exactly the care I need, and addresses the 360 degrees of what is involved for my health. I even enjoy the visits with her because watching an artist at her craft is a pleasure. I left feeling like my health was on track and I had a plan to keep it there.
I feel privileged and very grateful that Dr. Morioka is my physician. She consistently exceeds my expectations. She is so good that she could teach Nordstrom's about customer care!
Best doctor at Stanford!
First time visit with Dr. Morioka. I was impressed with all her knowledge and positive attitude. I found more healing in her inspirational words, than I did in the medicines that she prescribed. Dear Dr. Morioka thanks for adding a human touch to my treatment!
Dr. Marioka was very comprehensive and compassionate. She empathized with how I was feeling and was very clear on the examination process.
Dr. Morioka is superb!
My english is not a good one, but dasn't exist problems
Dr. Morioka-Douglas is awesome!
Dr. Moriaka-Douglas rocks.
Dr. Morioka-Douglas was extremely thorough and took time to explain things to me. Nice of her to document a summary of my check-up too.
Great amount of time spent great discussion.
I would recommend Dr. Morioka anytime but recommending Stanford is whole different story. I have had nothing but bad experience with the Stanford system except my primary physician's office. The specialties clinics are a whole different story. Ophthalmology specially.
Dr. Morioka is one of the best MD's I've ever known. She is always so caring and concerned. She really goes above and beyond all my expectations. I will have a hard when and if she retires.
Dr. Morioka is the best she "rocks."
dr morioka- best doctor i've ever had!
Dr. Nancy Morioka-Douglas is an excellent provider.
Dr. Morioka-Douglas is hands down the BEST doctor I have ever found. All of the above questions should be given even higher than the "very good" option. She is engaged, informative, friendly, unrushed, talks in understandable terms, provides tons of information, genuinely caring, etc. Absolutely the best doctor.
I have been seeing Dr. Morioka as my Primary Care Physician since 1994 and I have always felt confident that she had my best interest as her focus. I have seen her mature as an MD service provider who has allowed for many ways to define, understand and provide what will meet my individual Medical needs from a physical, emotional, spiritual,and professional perspective as she has taken the time to know me as a whole person and care about me with compassion by helping to facilitate more integrated, holistic solutions to support my health care needs. This approach has kept me coming back to see her even after I retired from Silicon Valley and went to Paso Robles to live my retirement dream.
Fantastic family practitioner. So happy to be her patient again.
Dr. Morioka-Douglas' care is always excellent.
Was nearly given an inoculation I was allergic to. It was in MyHealth record but doc didn't know! THIS IS SERIOUS!!
I have been seeing Dr. Morioka for 20 years. She is, without a doubt, the best medical provider I have ever had. She is patient, listens well, explains clearly and is a caring, wonderful person.
dr Morioka-Douglas is great! She is so thorough, caring and super knowledgable. she is always good about answering my emails.
Dr. Morika-Douglas always takes extra time to look at my entire medical chart and go over each individual medication I take on a daily basis. She confers with Dr. Sklarin on my thyroid medication and we always discusses my iron regime since I am anemic. Dr. Morika-Douglas is a thorough doctor!
I have not heard from Dr.Morioka since my xrays.
Dr. Morioka-Douglas is absolutely the most caring and knowledgeable physician that I know. I've been going to her for over 20 years and I would never want to go to someone else as long as she's practicing.
My care provider has always given me excellent care and always spends time listening to my concerns if I have them.
Dr. Morioka is the best!
I was fortunate to find Dr. Morioka about 23 years ago. She is the first doctor who remembered me on a return visit and seemed to truly care about my health. Over the years, she keeps up with changes in my life and somehow remembers details about my family and my experiences. She is amazing. I have seen other doctors, even in the Stanford Family practice, who I refuse to see again. Once I experienced the quality care that she provides, I no longer wanted to tolerate the attitude and impatience of the other doctor with whom I had a poor experiences. (She was my obgyn during my first pregnancy) Dr. Morioka is the best doctor for me, and I drive the extra distance to see her on the das that she is in the office.
I have already recommended Dr. Morioka-Douglas to family & friends. They are now patients of her.
I saw this doctor twice. Both time she is in a rush & rush through the whole exam. My questions seems to annoy her.
Dr. Morioka is much more than a provider... she is a friend, a counselor...
It's helpful to use the internet to communicate with my provider.
Dr. was rushed ended appointment before all my concerns/questions were addressed (I was asking her questions as she walked out the door) AND she didn't follow up/even after reminding her via My Health") on referrals.
Dr. Morioka is very knowledgeable & displayed concerns for both physical & mental well being of the patient. However, I feel at times she seemed dismissive of possibility of problems based on a excellent health history (patients).
The doctor didn't treat me and referred me to 3 specialists I got cured at home without going to any specialist.
She was gentle, smiling & caring though I met my doctor for the first time.
This provider was outstanding! Her recommendations were evidence-based and practical.
Dr. Morioka is the BEST.
Dr. Nancy Moriok-Douglas is the BEST.
Excellent physician!
