Doctor Mateer at L.I. Orthodontics is the best doctor we have ever met across all medical practices. He is professional, compassionate, kind, very knowledgeable, poised and empathetic. He has a great sense of humor and cares about each of his patients. He certainly fits the level of Best Doctor in New York or even at a broader spectrum. He is probably the ONLY doctor who does not have $ signs in his face as the main goal for the practice. We hope Doctor Mateer never changes.

He is so caring and nice I hate all doctors/dentists but I actually look forward to the orthodontist with him. He is patient understanding funny nice/kind.

The best Dr by far. In everyway.. funny personable I've never had a dr that was on time Everytime with an appointment

Dr. Mateer is AWESOME...he is honest, very personable, kids love him, he always remembers and asks what they are up to, which makes them feel very special. He doesn't rush you out of his office, takes his time to explain and answer any questions. Richie and Alissa are VERY HAPPY
