Dr O鈥橬eill was exceptional. Very personable, listens and explains status and plan.

08/06/2024

The provider was down to earth and caring about my feelings. Explained my disease in a way I could understand and made me feel much better about it. She knew how bad I needed to get the surgery over with and got me in very fast!! I left the office feeling so much better. I highly recommend dr. Oneil.

I was made to feel that I was an active part of my care team and that my decisions were accepted and respected even when they did not always follow recommendations. I felt like I had control over my healthcare.
