    Our visit was precautionary. In the time it took to get an appointment we had already figured out the issue we were having. We kept the appointment just to make sure the GI doctor didn't see a reason for further tests.

  • October 21, 2025

    Everyone at the front desk, the nurse that got us settled in, and of course Dr. Feist for his patience explaining everything to use (and directly to my 10 year old who was very concerned about what is coming next).

    We are just very pleased overall. I received a call from the woman in scheduling, she was very good about giving me information like address, directions for finding the office, helped me set up the app and just made sure this first interaction would be easy. The woman that checked us in was very nice as well. We got in before our appointment time vs a long wait which rarely happens in most doctors offices. The nurse was really nice as well. It was a great experience and I would definitely recommend others to them. Thank you so much.
