I am most passionate about restoring patients’ oral health in a low-stress environment. Treating anxious people who may have stayed away from the dentist for years, and helping them become great dental patients, is my goal. I love the practice of dentistry and enjoy giving exceptional care to all my patients in a calm and caring environment. Dentistry has provided me and my family with a great life and gives me opportunities to meet new people every day.

Originally from Medford, Long Island, I now live in Dracut with my wife Alecia, our son Jack, our daughter Emma, and our cat named Louise. I run daily and am a huge sports fan, especially of the New York Yankees and New York Giants. Being active in the community is important because it gives me a chance to give back. I volunteer at my son and daughter’s school and actively give to charity organizations in my area.

Matthew Hickin, DDS MS

Periodontist

Dentistry is an exciting yet challenging field, but I truly enjoy every day of practice. Periodontics in particular is a fascinating field that is constantly changing and updating. New research and technology is changing the way periodontists treat patients, with increasing comfort and efficacy. And while I am passionate about saving teeth, dental implants have allowed for treatment not possible in the past and is an integral part of my practice.
