Wonderful experience. I'm so scared of needle but Dr O'HALLORANS ASSISTANT took vial if fluid out of my k ee then a steroid injection. Never felt anything!!!
January 16, 2025Mary C.Verified patient
The office experience was great, the wait time was good, and the staff was very friendly and organized. What I didn't like was the doctor didn't give me instructions on what to do, how to not aggravate the problem, what I can do to alleviate the issue on my own besides physical therapy, and was hesitant to answer my questions on preventing injuries.

The staff at the medical clinic were exceptionally friendly. The clinic was extremely well-organized, and all procedures were carried out with remarkable smoothness.

Fantastic bedside manner. Took the time to learn a bit about me as well as the injury I was trying to heal. Really appreciated how disarming his personality was during the examination.
