MATTHEW C. LEIGHTON D.D.S. in Amherst, NH | Ponemah Crossing Dental, P.C.

Matthew C. Leighton D.D.S.

Originally from Vestal, NY, I grew up in a family of seven with a sister and three brothers. My father and mother instilled in me the value of higher education and health professions at home and as a clerk in their pharmacy business. I quickly learned how to provide customer service and the value of relationships with our customers.

I received my Bachelor’s Degree in Mechanical Engineering from Rochester Institute of Technology in 1989 and worked in a nuclear power plant before returning to college life to become a dentist, a dream I have had since the age of eleven. I received my Doctorate of Dental Surgery from SUNY Buffalo School of Dental Medicine in 1994, then a residency certificate in General Practice from St. Clare’s Hospital, Schenectady, NY, in 1995. I returned to my hometown to practice for a few years, then moved to Amherst, NH, with my wife Cathy, and joined doctors Kayser and Clark in 1998.

I have worked tirelessly to deliver the highest-quality dentistry to our practice’s patients and provide a safe and comfortable environment for them and our team. Our team’s level of customer service is unsurpassed in our community.

Dedicated to lifelong learning, I attend continuing education and participate in study clubs to keep abreast of the latest advancements and treatment techniques. I am a Dawson Alumni and a member of Spear. I am a member of the American Dental Association, the New Hampshire Dental Society, and the Nashua Dental Society.

Outside of my professional life, I give back to the community as a board member for the Northern New England chapter of the Cystic Fibrosis Foundation, I volunteer as a coach for my son’s Ice Hockey team, I am an adult leader with Amherst Boy Scout Troop 613, and I strive to be the best husband and father my family could ask for.
