Dr. Greenberg was born and raised in Nassau County, New York. He earned both his Bachelor of Science in Accounting and Master of Business Administration (MBA) from Binghamton University before pursuing his passion for dentistry.
He received his Doctor of Dental Surgery (DDS) degree from Stony Brook University School of Dental Medicine in 2022. During his time at Stony Brook, he lived in Port Jefferson, where he developed a strong connection to the local community.
After dental school, Dr. Greenberg completed a General Practice Residency at North Shore University Hospital in Manhasset, New York. He continued his training as Chief Resident before completing an Implant Dentistry and Advanced Prosthodontics Fellowship.
His advanced education allows him to provide comprehensive restorative, prosthetic, and implant dentistry with confidence and precision.









Dr. Greenberg believes exceptional dentistry goes beyond treating teeth—it's about building trust and lasting relationships. He stays current with the latest techniques and technology to ensure every patient receives modern, personalized care tailored to their unique needs.
His goal is simple: to help every patient leave the office with a healthier smile and a positive dental experience.
When he's not caring for patients, Dr. Greenberg enjoys spending time with his wife and their dog, Roger.
He's a dedicated New York sports fan, cheering on the Mets, Jets, Knicks, and Islanders. You'll also find him on the golf course, playing racquet sports, listening to country music, or spending quality time with family and friends.
