    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.

    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.

    The delay in getting appointment is frustrating. Providers are overbooked and patient load too large

    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.
