She was excellent. She goes the extra mile, beyond what she doesn't even have to do. She's a wonderful provider.

Dr Wexler is one of the best physicians I've had. She is very intelligent and methodical in her approach to my care and treatment.

I LOVE Dr. Wexler!! I have a lot of doctors and she is by far my favorite. She listens, she follows up, she creates a clear plan to move forward, she is encouraging. Cannot say enough good things about her!!!


April 2025

I have been with Dr. Wexler for close to 20 years. She still amazes me every time I see her. This last visit I was amazed that she had read all of the documentation, all of the paperwork done by my cancer team, and she knew as much about my cancer treatments as I did. She's an amazing doctor and she's a credit to Mass. General Brigham.

Dr. Wexler is always so respectful of me and isn't condescending at all when she explains things to me.

Dr. Wexler is an outstanding physician, great diagnostician, very sympathetic, listens carefully, gets back to me when I need to speak to her, and I would rate her as a 10.

she was very warm and friendly. she was helpful with the questions I had about my health and she gave me specific information about my condition. and she told me about compression socks and elevating my legs when I am sitting.

Dr. Wexler is always informative, knowledgeable, directive, comforting, reassuring, and supportive. I love her bedside manner, so to speak. She is the best and I just love that I have her as my doctor.

Dr Wexler is the best -- she explains everything, listens to all my questions. I never feel rushed. She makes me feel confident in how I am handling my diabetes. She tailors my management to meet my lifestyle.

She's great. Explained what my goals should be. What I should do if it's not working. Things I can do to improve my glucose level.
