Could not have improved! Very grateful that they got me in within 24 hours of my call. I was very uncomfortable with a UTI. Dr. Riddle is not my usual gyn, but I know his fine reputation and was grateful for his quick care and solutions.

Amazing team
- 5 out of 5 starsReviewed on 8/28/2025
I was surprised that as a new patient that I was not asked to fill out my personal information and my medical history for the nurse, but after thinking about it I realized that due to my medical history with other doctors at Prisma Health, now all my information is in their system and available for any doctor to see and access. I liked Dr. Riddle. He was professional and polite.

Dr. Riddle does not have good bedside manners. My child is already nervous about being there and he did not ease her mind or nerves. She was unfamiliar with him and he treated her like she was just another number in a room which amplified her nervousness. He never saw her and did nothing to make sure she felt comfortable with a new doctor. The appointment was not complete and we had to schedule another one with a doctor that she's comfortable with.

No improvement is necessary. I received I-1 treatment.
