Good listener.

Timothy had reviewed medical records before the appointment. He spent time getting a good overview of health history. He made up a treatment plan that made sense . One of the best listeners that I have ever had.

He listened and explained things. He did not make me feel rushed or unheard.

I enjoyed meeting Tim and working with him. The only negative thing was waiting for an appointment! Originally had a February 2025 appointment and waited until November 2025 for a follow up appointment . That seems unacceptable to me!!!

I have seen Timothy for several years. I have communicated with him through My Chart with questions and concerns along with office visits. He is very pleasant and easy to talk to. He always responds when I reach out to him. He takes time to listen. I really appreciate that in him.

He listened intently to me explaining my problem. He ordered tests to rule out or confirm what's going on.

Easy to talk to/ good communication skills/ good "people skills"

The delay in getting appointment is frustrating. Providers are overbooked and patient load too large
- 5 out of 5 starsReviewed on 2/7/2025
Excellent
- 5 out of 5 starsReviewed on 1/9/2025
It took approximately 4 months to get an appointment, 2.5 months to get the testing required, and another 5 months for the follow up appointment. That’s a long time to be in limbo regarding one’s health.
