Get to know Dentist Dr. Stephen T. Deehan, who serves patients in Hackettstown, New Jersey.

Top dentist, Dr. Deehan, provides professional dentistry at his private practice in Hackettstown, New Jersey. Having been in practice for over 20 years, his goal is to continuously provide the highest quality of dentistry in a caring and nurturing environment

A firm believer that everyone deserves a healthy and beautiful smile that lasts a lifetime, he strives to create an atmosphere where all employees work to create a harmonious and professional relationship between each other as well as with the patients. His ultimate desire is to provide a most enjoyable experience for each patient for the care and treatment they need to maintain excellent overall oral and total body health.

A 1993 graduate of the University of Medicine and Dentistry of New Jersey, Dr. Deehan accomplished a one-year residency at Overlook Hospital in Summit. He then opened his practice in Hackettstown in January of 1996.

Over the years, he has become certified in various fields to educate himself on the proper care needed to provide overall oral health for each and every patient. He is a member of the Tri-County Dental Society, the American Dental Association, and the New Jersey Dental Association. He also participates in a monthly SPEAR educational dental study club with peers to stay current with the technology and treatment in the realm of dentistry today.

Dentistry, also known as Dental and Oral Medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity. Dentists diagnose and treat dental issues and help patients develop better oral hygiene regimens. They clean teeth, correct bite issues, perform surgeries and extractions, and perform other duties to ensure that the teeth and mouth are healthy. 

Married for over 20 years and a father of four, Dr. Deehan enjoys his weekends spending time with his family. He has been a coach for each of his children, has taught catholic education at his local church, and has taught dental health in local schools. Although wrestling is by far his favorite sport, he likes keeping up with all high school, college, and pro sports. His favorite time is spent hanging with his children either on a field or at his home and it almost always includes hot wings.
