Dr. Matthew S. Heimbach

Dr. Matt was raised in Berwick, Pennsylvania. When he was 8 years old, his aunt needed all her teeth extracted, allowing him to witness the changes in her quality of life, including her inability to speak or eat healthy foods. Dr. Matt was intrigued and began a mentorship with his general dentist at the time, inspiring his dental career at a young age. While earning his undergraduate degree in Biology at Susquehanna University, Dr. Matt was a four year letterman for the Crusader basketball team. He then attended Temple University’s Martin Kronberg School of Dentistry, the second oldest dental school, where he earned a scholarship with the United States Air Force.

Following graduation from dental school, Dr. Matt attended Officer Training School, where he earned the rank of Captain and was appointed Vice Commander. In 2001, Dr. Matt completed a one year residency in Advanced Education in General Dentistry, spending his time being individually trained by board certified specialists in surgery, periodontics, prosthodontics and endodontics. During this time at Kessler Air Force Base in Biloxi, Mississippi, he was honored as the Chief Resident and was awarded his anesthesia credentials, enabling him to provide both sedation and surgical care to his patients. Dr. Matt furthered his surgical skills on a humanitarian mission to Guatemala with a team of physicians in 2003. Dr. Matt spent the next two years honing his dental and surfing skills in Santa Barbara, California while stationed at Vandenberg Air Force Base.

Dr. Matt was honorably discharged from the Air Force in 2004, returning to the east coast to work at several large dental practices throughout the state of New Hampshire, focusing on digital dentistry, wisdom tooth extraction and grafting and implant procedures. In 2008, Dr. Matt decided he wanted to practice closer to his home on the seacoast, inspiring him to start Abenaki Dental Care in Exeter, New Hampshire, and allowing him to provide comprehensive dental care to the local community. Dr. Matt furthered his education in 2012 when he completed a surgical fellowship in implant dentistry with world renowned implant expert Dr. Carl E. Misch in Orlando, Florida, where he achieved fellow status at the Misch International Implant Institute (MIII) and was inducted into both the Implant Prosthetic and Surgical sections of the International Congress of Oral Implantologists (ICOI). In 2016, Dr. Matt completed a mini-residency at the Craniofacial Pain Center at Tufts University School of Dental Medicine, expanding his knowledge on TMJ disorders and sleep apnea. He now works closely with local sleep specialists to develop solutions for our CPAP-intolerant patients. Dr. Matt continued his quest for dental knowledge in 2018 when he completed a mini-residency in state-of-the-art endodontics with Dr. John West at the Interdisciplinary Dental Education Academy (IDEA).

Dr. Timothy S. Ahern

Dr. Tim was born and raised in New Hampshire and has been a proud New Englander ever since. He earned his undergraduate degree in Biology in 2013 at the College of the Holy Cross in Worcester, Massachusetts. Dr. Tim spent his extracurricular time volunteering for the Special Olympics and weekly Unified Sports events on campus, which helped him come to the realization that a career where he could treat people was in his future.

During his summers off from college, Dr. Tim was able to work side by side with his father, Dr. John J. Ahern, DDS, and even with Dr. Matt here at Abenaki Dental Care. He immediately admired the artistry, finesse and skill each dental procedure required. More importantly, he loved witnessing the relationships develop between these men and their countless patients.

Tufts University School of Dental Medicine gave Dr. Tim the most profound experience of self-discovery he could have ever wished for as he immersed himself in the community, volunteering his service with the Tufts Medical Psychiatric Residency Program and the Josiah Quincy School in Boston. He also had the humbling opportunity to spend externship hours at Community Dental Care of Claremont in New Hampshire, shedding light on the impact he could have on his state. Dr. Tim was the proud recipient of the Northeast Delta Dental Endowed Scholarship. At Tufts Dental School, nothing is stressed higher than chairside demeanor. All students possess the hand and mental skills to be dentists, but those who truly wish to be great must utilize their people skills from within. Dr. Tim had the privilege of learning what it meant to be a great dentist under the likes of Drs. Alan Epstein, Mary Karish, Mark Caddell, James Theodore, Ala Ali, Pilar Sanchez, Brendan Prindiville, Richard Doff, Linda Marinello, John Ricci, and many others. Dr. Tim strives to stay at the forefront of dental technology and in 2018 has completed advanced courses in CEREC dentistry and invisalign®.
