Gregory L Baker DDS

Meet Dr. Baker

It is my pleasure to provide my patients with top-of-the-line orthodontic care. One of the areas that interests me the most when it comes to my practice is working with young patients. It is difficult enough to be an adolescent, and throwing orthodontics into the mix makes it even more complicated. I strive to do the best job possible to help them through this phase. After 29 years practicing orthodontics, I believe that I have both the professional and empathetic touch to assist all of my patients when it comes to giving them the beautiful smiles they deserve.

Education and Continuing Education

  • Bachelor of Science Degree – Pennsylvania State University
  • Doctorate of Dental Surgery – Temple School of Dentistry
  • Orthodontic Certification – University of Pennsylvania

As a firm believer in continuing education, I am a member of the Roth Williams International Orthodontics Society. In 2011, I was involved in a five-week training program with the Roth Williams International Group, focusing on new techniques in the orthodontic field, including accelerated orthodontic treatment. Additionally, as an associate clinical professor of orthodontics at Harvard School of Dental Medicine, I am passionate about learning new techniques and passing this knowledge on to both my students and those who come for treatment at the office.

Professional Affiliations

My professional affiliations keep me current with the newest advances in the industry. These include:

  • American Association of Orthodontics
  • New Hampshire Dental Society
  • Roth Williams International Society of Orthodontics
  • Bioesthetic Dental Institute

Something Personal

I am a native of Lawrenceville, PA, and have lived in Hanover, NH for 20 years. I have two sons, including one who is enrolled in a dental residency program at Eastman Dental Center in Rochester, NY. He will join our practice when he is ready. I have one daughter-in-law and two grandchildren, ages four and two.

When I’m not working, some of my leisure activities include playing the saxophone, skiing, kayaking, and hiking. As a believer in giving back to the community, I am passionate about land preservation, and am also a volunteer at the Red Logan Dental Clinic, providing dental care to underprivileged patients.
