Meet Dr. John Ahern

I have been blessed to be a dentist for nearly 35 years. I have watched the children of some of my early patients have children and bring them to me for care. These generational relationships, and the continuity of strengthening those connections at regular visits, mean the world to me.

Now I am savoring the opportunity to continue my profession while working with my son, Dr. Tim, and my longtime colleague and friend, Dr. Matt.

I began practicing in 1985, drawn to the profession as a way to help people lead healthier and happier lives. I appreciate the intricate details of dentistry, the need to design treatment to each person’s specific concerns, and — most of all — the relationships that naturally develop.

Professionally, I am particularly interested in crowns and bridges, as well as removable prosthodontics. Restoring stability and function allows a person to eat the foods they love, and gives them the confidence to smile.

Each day I help people, whether that’s removing pain, brightening a smile, or offering education and encouragement as they develop better oral hygiene. I cannot imagine a more fulfilling profession.

Education and Professional Affiliations

I completed my undergraduate studies, culminating in a Bachelor of Arts degree, at the College of the Holy Cross in Worcester, Massachusetts. Then I attended Georgetown Dental University, where I was awarded my Doctorate of Dental Surgery.

In the years since I finished dental school and entered into private practice, there have been remarkable changes in dentistry. We now utilize revolutionary technologies, wholly new methodologies, and advanced materials. These research-driven developments improve diagnostics, treatment, and results, while making procedures more comfortable and efficient.

I am committed to staying up to date on the latest technological and treatment protocol changes in order to provide patients with the best of modern dentistry.

As an active member of the American Dental Association, New Hampshire Dental Society, and Granite State Study Club, I have access to the latest information. Taking courses, and attending meetings, lectures, and seminars, ensures I am current on the newest options and able to incorporate the best into patient care.

Beyond the Practice

I grew up in North Syracuse, New York, and have lived in Londonderry with my family for the past three decades and more.

Karen, my wife, and I were married in 1982. We have three sons: Ryan, Cory, and Timothy (Dr. Tim). Ryan and his wife, Kate, have two beautiful daughters, Celeste and Noelle; Dr. Tim and his wife, Katie, have a beautiful daughter, Daphne.

Karen and I are enjoying being grandparents and spend as much time as we can with family. I also try to find time to golf.

I have always felt it is essential to give back to and strengthen the community. I have been a board member of the Derry Boys and Girls Club since 1985 and am proud of children we have assisted. The organization serves more than 2,500 children a year, regardless of their family’s financial abilities. It is very important to me that we keep all of these services affordable, and to offer a safe and nurturing place where kids are part of a caring community.

In addition to my work with the Derry Boys and Girls Club, coaching has been a large part of my life. I enjoyed coaching recreational and Little League programs in Londonderry. I was also an assistant varsity football coach at Bishop Guertin for 18 years, and an active member of the Holy Cross Varsity Club.
