Comment - “ Dr. Herzog was very professional... ”

Dr. Herzog was very professional. Though he couldn't really tell me the possible reason for my knee pain (admitted he didn't know). X-ray showed nothing obviously wrong. He suggested I could try PT, but wasn't sure it would help. Gave me option.

Good Interaction with assistant and doctor. They were responsive, respectful, and very clear. They listened and answered all of my questions-genuinely cared about my issue.
