    He seemed rushed and barely spoke to me

  • Feb 15, 2022

    was not pleased with Dr. Ferris. I wanted to know why these pains were moving and he continued to investigate pains that were gone days ago. He also told me he didn't go through email and only saw people in person. People have questions or updates in symptoms that don't require a visit.

    Good information but rushed.
