Very impressed by Dr. Mallett. I surprised her with an unexpected problem. She very quickly came up with a diagnostic and therapeutic plan. Saved a long-planned and expensive vacation. I'm very grateful for her expeditious and effective care.

Dr. Mallett was warm and easy to talk to regarding my medical concerns. She also had read my message and accompanying data and had looked into the issue so was prepared to discuss. I recommend her to my family and friends.

She's a new care provider for me and I used to have George Couset. I am very happy with her. I really enjoyed my time with George Couset, but she was equally up to his level as far as her care and communication and everything I'd be looking for. So very happy.

If I'm correct, her name was Dr. Mallett. She was a wonderful doctor. When I came home, I sat there, I made two phone calls and said I found the best doctor that anybody would ever want. And she is, she listened to me correctly. I should have went, you know, I had a few problems, but like I said, she listened to what I wanted, not what anybody else wanted. She listened to what I wanted. She cared about what I wanted. And that is exactly what you guys need because I have had some bad experiences over there.

My experience with Dr. Mallett was fantastic. She listened to everything I had to say, gave me recommendations. She was very congenial, communicated well with the nurses, and I think I just recommended her to my wife. So all that said, the care at MGH in Gover has been exceptional. Thank you.
