Dr. Dean Saccomanno, DDS

The son of a registered nurse and a local ironworker, Dr. Saccomanno proudly comes from a “blue-collar” household from which he is the very first dentist in his family. When anyone asks Dr. Saccomanno what drew him into dentistry, his answer always stems from his upbringing and the way in which he was taught the basic value of ‘doing right by people.’ Dr. Saccomanno always says he saw a need in the healthcare field; that is, a need for more “down-to-earth” clinicians with the ability to relate to and connect with any patient who walks through the door.

As he and his childhood friend, Dr. Mastroianni, like to say, “When someone sits in our chair, it’s someone special. That person may be a mother, father, husband, brother, etcetera. There’s only one way to treat them – as family”. By keeping this idea at heart, these two friends have been given the rare opportunity to deliver a refreshing style of patient-care, one that strongly emphasizes compassion and respect rather than focused solely on the procedures and protocols of dentistry and endodontics.


In addition to being born and raised in Westchester County, Dr. Saccomanno kept his feet planted in his beloved New York as his education and professional training progressed. He obtained his Bachelor of Science Degree in Chemistry at Iona College in New Rochelle and continued to New York University to complete his pre-doctoral studies. Dr. Saccomanno completed his General Practice Residency at Jacobi Medical Center in the Bronx, whereby he returned to New York University to complete his specialty training in the field of Endodontics. Currently and throughout his residency years, Dr. Saccomanno has treated patients throughout Westchester, the Bronx, and Manhattan. He finds great joy in treating the very communities from which he and his family were brought up and looks forward to building genuine relationships within the town of Greenwich and surrounding neighborhoods.


When not practicing, Dr. Saccomanno truly enjoys his out of office routine, which includes daily physical training, evenings out with his partner, Briana, as well as spending quality time with his brother and mother, Thomas and Donna. Dr. Saccomanno, alongside his mother and late father, Tommy, have spent many active years in the fight against Duchenne Muscular Dystrophy (DMD). These efforts are dedicated to Dr. Saccomanno’s older brother, Thomas, with Donna being the co-founder of an international non-profit organization called Parent Project Muscular Dystrophy (PPMD). It is accurate to say that advocating and raising awareness for Duchenne is embedded in Dr. Saccomanno’s genes as he has had the privilege of learning from his older brother and watching him make great strides over the years. Dr. Saccomanno hopes to translate these ideas of patient advocacy and education to his practice of endodontics.
