This is my first visit with Dr Moynihan; she took the time to ask about my health and explained the steps she is taking (lab work, urine check) to insure she can monitor my overall health. She was calm, clear and was not in a hurry during my appointment .
Vary clear and through in explaining my condition and the workings of my medications. I have received excellent care.
This was my first visit w/this provider. She was fantastic explained my situation and future goals for next visit. She went step by step re: explanation of condition. I was able to learn a few things.
My visits are always informative. My physician is knowledgeable and spends time evaluating, explaining lab work and going forward making good suggestions.
Excellent care as ususal
Dr. always answers all questions thoroughly and explanations are understood. She has a very positive attitude.
very good
very good
I worked in hospital 30 years. I have a new doctor this visit and I was very pleased with Dr. Moynihan & feel very fortunate to be in her care.
I had a number of concerns about the quantity of vitamins/minerals Dr. Moynihan has recommended that I take, and she spent time to explain everything to me thoroughly. She also listened and responded in kind to some problems I had with message templates that she uses to communicate with her patients in MyHealth.
Very good.
My experience was wonderful from beginning until I left the building.
Dr. Clare takes the time to not only tell me what I can do to improve my A1C; she discusses in detail what happens within a person's body if they do follow her recomendations and what can happen if I do not. She is always friendly, smiles a lot which makes me feel not threatened. This attitude makes it easy to listen to her advise. Since no one is comfortable knowing they have diabetes, I learned early with her I do not have to be scared. Thus, I can listen better to her explanations.
it was the most professional & well planned discussions between client & Dr
I always have a great experience with Dr. Moynihan.
I have recommended my care given to my son.

I like Dr. Moynihan very much as she is very thorough & knowledgeable about my health concerns.
Best experience ever!
Clare Moynihan is a great doctor. I literally travel hours just to see her.
My doctor let me know how I was doing (progressing) and what she would like me to do to improve more. She explained my options and what would help my retinopathy problem the most. Her concern is always about me not losing my sight which I appreciate. My visit with her is always productive, informative and pleasant.
Dr. Moynihan was incredible to work with. I was very nervous going into my first appointment but she made me feel at ease right away and genuinely seemed to want to help. She was thorough with her explanations and walked me through everything step by step. She even apologized for the lack of lgbtqia+ options available on the forms (though I saw more options available here than at most facilities).
Dr. Moynihan, spent enormous and quality time explaining my health issues and concerns. She's very clear and concise. Highly recommended to anybody -

She is terrific, very clear and compassionate with good and not so good news. i understand her diagnoses, next steps, and possible outcomes!
I really like Dr. Moynihan. She is smart, friendly, and seems genuinely interested in my health. One suggestion: I would benefit if she could put her recommendations into writing and include them in my after-visit summary. I always have to take a lot of notes about what I should do with meds, labs, etc. because she doesn't give me that info in writing.
Dr. Moynihan is warm, smart & a good listener. I have recommended her to other friends.
I have ben with this provider for years and have high confidence in her skills
Dr. Moynihan is terrific. Attentive, great sense of humor, excellent care. 5 Star diabetes care!
dr Moynihan is one of the best
The MAIN THING I LOVE ABOUT DOCTOR MOYNIHAN SHE IS A STRAIGHT SHOOTER. I am not a good patient, following instructions, keeping appointments, doing my part, however she makes me feel like I am IMPORTANT. Remembers what we discussed previously, sometimes I had forgotten.
I consider my problem to be a serious one and did not feel the provider gave me the time I needed. I felt that the nature of my problem needed a somewhat more holistic approach - that is to look at all my health problems as a clue to what happened that brought me to the doctor - I broke a bone for no apparent reason.
Very good to have Dr. Moynihan as a provider.
Dr. Moynihan was professional and friendly. She answered all my questions and gave me options on what will happen next. She is relatable and knowledgeable. I would recommend her to all my friends and family.

Elizabeth is excellent, she gives herself to the patients needs & is so loyal n what she does. I must say she works very hard & loves it.
Care provider did not seem to know about the latest research on recommended ratios of calcium/magnesium supplementation to treat osteoporosis.
I like my doctor. She has a good bedside manner, very caring and patient.
She explained things so well I had NO questions.
Never feel rushed and Doctor Moynihan takes time to answer all my questions and makes me feel like I'm seeing a friend rather than my care provider.
I really like Dr. Moynihan. She listens and explains very well in person, during an office visit. However, contacting her thru MyHealth is hit-or-miss. Sometimes she answers quickly, other times 2 business days will pass with no response and I have to call her office and leave a message for her to reply.
Friendly kind, concerned meet my need.
Dr. Moynihan is the best.
The doctor is a gem. She is very intelligent, caring and attentive, both in coordinating her care with my other providers and checking their notes as well as my own observations.
Dr. Elizabeth Moynihan was more than very thorough. She was exceptional both in her approach to my condition and extent of time spent explaining treatment.:Absolutely empathetic and professionally competent!
Very good!
Dr. Moynikan was one of the best care providers we have seen. She took care to answer all our questions about my son's condition. She seemed very knowledgeable as well.
On several occasions I have recommended the Dr.
first comment by Dr. Moynihan was "my assistant tells me you have 1 million questions so know that we only have 20 minutes." This startled both my wife and me but we did recover and carry on and what little time we had left. This problem traces back to the lack of allowing time in the appointment for getting the perfunctory intake technician work done before the doctor gives you her full attention for the full 40 minutes. I am still trying to get to understand and trust Dr. Moynihan but I think we will get there in time if we can understand the system better and learn how to make it work for us instead of against us.
I really like Dr. Moynihan. She is incredibly kind and understanding. I really felt like I had someone on my "side" as I moved through my cancer process. She listens to my questions and concerns and she gives very clear answers. She responds to email through the MyHealth portal very quickly. There was a point when I was corresponding with her quite frequently and she didn't tire of my questions.

Dr. Moynihan is really helpful and I appreciate her clear answers and thoughtful explanations.

Dr. Moynihan is an excellent physician.
I was impressed by the doctor's up to date and detailed knowledge.
Down to earth. Doing what's needed. Explained that she may not be able to complete the biopsy due to a lack of fluid in the Thyroid Nodule. I might have to go to another facility where a pathologist would draw a biopsy sample. Fortunately that was not needed. But it was nice to be included in her thinking.
She had actually prepped for our visit, reading the chart the night before. My records had not been transferred, and she got them right there & then, we researched treatments- excellent care.
Professional and compassionate.
