After graduating from The Johns Hopkins University with a degree in natural sciences, Dr. Schoenberg entered The Medical College of Virginia School of Dentistry. His interest in the medically compromised patient caused him to pursue additional training; while in dental school, he externed at several hospitals through the United States. Upon completion of his dental training, his commitment to this special population continued as he undertook a dental general practice residency at The Mount Sinai Medical Center of Cleveland, Ohio. After several years of private practice experience, Dr. Schoenberg joined the staff of Visiting Dental Associates.

Dr. Schoenberg is a member of the American Dental Association, the Academy of General Dentistry, the Academy of Dentistry for the Handicapped, and the American Society for Geriatric Dentistry.
