Dr. Gregory Baker
I’ve been practicing in New Hampshire for over 35 years and it is my pleasure to provide my patients with top-of-the-line orthodontic care. As a firm believer in continuing education, I have become a Platinum-level Invisalign provider, am a member of the Roth Williams International Society of Orthodontics, and serve as associate clinical professor of orthodontics at Harvard School of Dental Medicine. I am passionate about learning new procedures and techniques to the benefit of both my patients and my students.
