As has been the case in every interaction I've had at MGH, I was treated with courtesy and respect and was seen promptly and on schedule. Dr Flint is careful and thorough and wants to be sure that she is communicating with me.

Dr. Flint was very well versed on my history. She was aware of all the meds I'm taking and we went over some options for med changes in the future and also timing-wise. She listened very intently. I think she's a great doctor and I really feel comfortable working with her. Thank you.

Dr. Flint was very caring, concerned and had reviewed my previous health issues pertaining to my parathyroid surgery and lab results surrounding it. She reviewed with me the results of the DXA scan I had done that day and gave me explanations I could understand. She gave me suggestions on how I could improve a couple of health problems I have and gave me reasons good enough for me to want to try them. I'm happy to have her as my new endocrinologist!!

Dr. Flint is a wonderful physician. She's so competent and so patient. I've now seen her in person and I've seen her over video connection and she's followed up checking on how certain medications were doing or not doing and making adjustments and I consider myself very, very grateful to be her patient.

This was my first meeting with Dr. Flint. She had reviewed my medical history and was aware of all the important factors that needed to be discussed during our discussion of treatment for osteoporosis. Although I'd talked with three other physicians (1 orthopedic surgeon and 2 rheumatologists) about this treatment, none of them explained the treatment with the same depth of information that Dr. Flint provided. She was patient, listened to my concerns, answered all my questions, treated me with respect. I feel grateful to be under Dr. Flint's care. She is highly skilled, personable, and thorough. A winning combination! Thank you.

I'm so glad I got to see Dr. Flint after my sudden diagnosis of LADA. I really appreciated that she started by asking me what I knew about it, and filled in the details or corrected my understanding if I got things wrong. She understood my drive to find some way to slow down or even halt the progression of the disease, and took the time to carefully review a clinical trial I found at another facility. I feel confident that she will be looking out for me throughout this process.

Remarkable how well Dr Flint understands my history!! She reviewed all medication with me. Fabulous that she explained a plan to monitor me , and exlained the capacity to direct any future interventions necessary. Within 24 hours I received her message reviewing labs drawn that day.
