I have only had 1 apt with Dr Petri for 15 minutes. So far I like her.
- 3 out of 5 starsReviewed on 10/22/2025
Everyone was very professional and courteous; however, I felt that the interaction came across as somewhat insincere. The provider spoke to me in a manner that felt condescending, as if I were being pacified rather than engaged in an adult conversation. I did not express any frustration or concern during the visit, so this approach felt unnecessary and somewhat demeaning. I would appreciate a more genuine and respectful communication style in future visits.
