Excellent doctor. Highly recommend.

The provider for GI was great. Her team was great. The hospital lab was an hour delayed and didn't say anything. That was a little frustrating not knowing it would be that long of a wait.

Base on our experience, it was excellent service. The nurse and the doctor treated us well even when we can not explain ourselves well. To that I will give 5 stars

Dr. R is very personable and thorough. Very rare when a Doctor will take the time to call, explain test results, and treat you like a human versus a my chart number. I really appreciate her humanity and care.
