A lifelong hobbyist and ceramist, Dr. Mambrino knew early on that his future work would involve designing and engineering on an advanced level. Dr. Mambrino grew up in Westchester, New York. At 13 years old, he went to work at a local hobby shop. He spent long hours after school and weekends designing and building ¼ scale RC boats that would ultimately compete on a national level.

Dr. Mambrino completed his undergraduate studies at Lehigh University where he earned both a B.A. in Biology and an M.S. in biochemistry. He went on to proudly earn his Doctorate of Dental Science at New York University College of Dentistry. In 2002, Dr. Mambrino moved to Southampton, New York. He began his career at the dental practice he now owns and operates. Dr. Mambrino and his team offer a comprehensive approach to dental health, intersecting beauty and function.

Dr. Mambrino prides himself on his attention to detail and his ability to communicate effectively with his patients. Patient education and comfort are important components for the execution and completion of any dental procedure.
An avid fisherman and conservationist, Dr. Mambrino resides in East Quogue, New York.
