Since retiring from the physical practice of dentistry in December of 2020, Dr. Dubin has continued to mentor doctors serving patients through District Mobile Dental, LLC. He has also continued his education in the care of patients with disabilities and impairments through the University of Pennsylvania School of Dental Medicine Office of Continuing Education. A series of courses, through the professional development program, will grant Dr. Dubin certification as a Disabilities Dentistry Clinician Expert. This certification encompasses many hours of continuing education with the goal of helping to improve access to dental care for individuals with disabilities and impairments.
