• Dr Simmons has been my families PCP for many years. She is an excellent doctor and she has all my trust.

• Dr. Simmons was totally excellent. I made one mistake on my response. I think it was the timeliness of the appointment, whether I was treated in a timely way at the appointment. I think I accidentally pressed no, but it was totally fine. It should have been a four. But overall, it was an excellent experience.

  2026-07-08

• Absolutely excellent!

  2026-07-04

• Dr. Simmons is the kind of doctor everyone should have: kind, down-to-earth, unflappable, expert, calm yet cheerful, willing to refer you to another doctor for more expert care if needed. She follows up immediately on tests, and is very available by Gateway messaging. If I could rate her a 1000 instead of 10, I would! Please do everything you can to keep her at MassBrigham

• I think Dr. Simmons is so good. I mean, in our annual appointment, she is never rushed. She always asks me first what's on my mind. She always goes through updated family history, spends time on anything I have going on. And then earlier this year, I had a serious medical occurrence out of state. And then I had some maybe repercussions or something came back and I wasn't sure what it was. She, whenever I emailed her, followed up by email. She followed up with phone calls and was very responsive and efficient. And she's been my doctor for a long time and I think she, and my husband's as well. And we think very, very highly of her.
