Patient verified via Press Ganey

I have been a patient for many years. Dr. Zimmer is very caring and engaged in my care. She takes the time to explain medical situations and outcomes for medication or treatment. I have known her to be especially present when my husband was dying as she was also his caregiver. There could not be a better internist for me than Dr. Zimmer.

Overall Rating: 5.0 2025-10-01

Patient verified via Press Ganey

She took the time necessary to address all of my questions, she looked back in my chart to address any issues that we had had during the prior visit, and she was very nice and friendly during the whole appointment! I really like my doctor!
