Dr. Max Blondman

General and Cosmetic Dentistry



Dr. Max Blondman was born and raised in Great Neck, New York. Besides being an avid golfer, he grew up drawing, painting and sculpting. Dr. Blondman completed his undergraduate education at the University of Miami, with a bachelor’s in Architecture, graduating Cum Laude. Despite his aptitude in architecture, he realized that he wanted more personal interaction with new people on an everyday basis while still being able to use his visual and manual skills. Having grown up in a family of dentists, Dr. Blondman changed focus and found dentistry to be the perfect fit, with the added benefit of drawing on the knowledge and experience of his parents! 

Dr. Blondman attended NYU College of Dentistry and completed his residency at the VA Medical Hospital in Manhattan. He has subsequently completed a two-year course at NYU and received a certification in placing and restoring dental implants. Dr. Blondman’s eye for detail makes him uniquely qualified to tackle complex cosmetic cases as well.

Dr. Blondman now lives in Manhattan, with his wife, Sabrina, and adorable son, Jack, and dog, Hudson. Dr. Blondman is a big sports fan, so you can often find him at Citi Field or MetLife Stadium, cheering (through a frown) for the Mets or Jets.
