Best place to go and best doctors.


March 2025

This was a follow up appointment after a hospital stay where I was being followed by this care provider. Everything was explained to me in a way that I could understand, and Dr. ANDREW ALLEGRETTI is a very thorough and pleasant doctor to interact with.


March 2025

Woman at front never acknowledged my presence when I tried to check it. She finally mumbled something from behind her computer screen but never made eye contact during the interaction. She remained hidden behind computer screen. She was not there when I tried to check out and after waiting a few minutes, I left.


February 2025

The receptionist and Doctor were easy to deal with. The nurse was hard to understand.


November 2024

I had a great experience at the Mass General with Dr. Allegretti. He saw me at Timely Manor. The nurse that came in was nice. He explained everything to me, went over everything. He did a great job. He's a fabulous doctor. [redacted]
