Meet Dr. Seylar

Dr. John E. Seylar grew up in Queens and knew, from a very young age, that he wanted to be a dentist. He attended New York University College of Dentistry, where he was awarded his Doctorate of Dental Surgery.

After completing dental school, Dr. Seylar briefly practiced in Westchester and Roslyn. Then he met Dr. William O’Shaughnessy and began a partnership of more than 30 years in their downtown Bay Shore family dental practice.

Dr. Seylar enjoys the variety of his days: caring for patients of all ages from different walks of life. For him, the bonds of friendship that develop with his patients and their families are the best part of his profession. He is committed to providing each patient with expert, individualized dental care, and helping them achieve the smile of their dreams.

Dr. Seylar and his wife Joanne live in West Islip, where they raised their two daughters. When he’s not working, Dr. Seylar enjoys being the “handyman” around his house and can often be found working on his latest home improvement project.
