Our Doctors

John E. Lagner, D.M.D.

Dr. Lagner grew up in Warwick, Rhode Island where he received his B.A. from Rhode Island College. He received his Doctor of Medical Dentistry (D.M.D.) degree from the University of Connecticut, followed by a general dentistry residency at SUNY Stony Brook. Upon completion of his residency, Dr. Lagner worked in Dr. Bonomo's practice for three years before assuming ownership of the practice.

The smooth transition of ownership from Dr. Bonomo to Dr. Lagner enabled Dr. Lagner to maintain the same level of care and compassion that the patients of the practice have always been accustomed to. When not in the office, Dr. Lagner serves as an assistant clinical professor at SUNY Stony Brook Dental School in the Advanced Education in General Dentistry program. He and his colleagues teach new residents current and advanced topics in general dentistry in a clinical setting.

Dr. Lagner is an active member and current President of the Suffolk County Dental Society, as well as the chairman of the New Dentist Committee. Under his leadership, this Committee's goals are to promote the advancement of superior standards and professionalism in all aspects of the field of dentistry. Dr. Lagner is highly skilled and experienced in providing the latest, most advanced dental treatments, including CEREC 3 and laser procedures for effective results with less pain.

Dr. Lagner and his wife Donna have two girls, Taylor and Cassandra, and one son, Jack. They recently moved to East Northport where they look forward to becoming active members of their community.
