Review by EILEEN ***** August 27, 2025

5/5
This was my first visit with Dr Gregory and her staff. My initial appointment wasn’t until mid Oct but Dr Gregory recognized a need to move my appointment up. I found Jamie to be very instrumental in getting the ball rolling. Dr Gregory is intelligent, thoughtful and punctual. She listened to my concerns and did a complete exam and review of my history. A great job by all. Thank you
