Dr. Leo has always called Suffolk County home and never strayed far from the tri-state area, even for his education. In 1992, he graduated from Chaminade High School in Mineola and moved on to Fairfield University in Fairfield, Connecticut where he achieved his Bachelor of Science degree. At New York University College of Dentistry, Dr. Leo earned his degree in dental surgery and graduated OKU Dental National Honor Society. For the next two years, Dr. Leo trained voluntarily at Staten Island University Hospital. During his second year there, he acted as Chief Dental Resident overseeing fourteen first year residents while furthering his education with advanced and difficult cases.
In 2001 Dr. Leo began working as an associate with his childhood friend and dentist, Dr. Arthur Marchiano. Dr. Marchiano retired in 2003 and Dr. Leo took over the practice at 2050 Deer Park Avenue in Deer Park, New York. He then served as an attending at Staten Island University Hospital while maintaining a full-time practice in Deer Park.
He works very closely with his partner in the practice, Dr. Koys, and numerous other staff members providing quality dental care in a clean, caring and modern setting. He enjoys all phases of dentistry and has stayed on the cutting edge of advanced dental techniques.
