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.

I've been going to Dr. Niehauser for 25 years now. He is a great Doctor. I get in with ease. He always listens to me. He explains things to me in a way I understand. I like the fact that he knows me after being my doctor for so long. Great doctor.
