Meet Gregory

I joined Mercy Health White Oak Primary Care in 2011. I’m so grateful to serve my neighbors, friends and their families by helping them be well. As a primary care provider to patients of all ages, I’m honored to be a part of our Westside community. When I’m not busy at work I enjoy many hobbies including golf, local sports, travel and theatre.

Great

I had 2 issues. By asking me about my symptoms, he determined I had a sinus infection and by looking at my chart, he prescribed amoxicillin. By coincidence, I had also hurt my lower back and side area. He prescribed the proper medication for that too.
