Mark J. Doherty DMD, MPH, CCPH , Founder

In Memoriam

It is with profound sadness that we announce the passing of our beloved Dr. Mark J. Doherty, on October 7, 2022 following a lengthy and difficult illness. Dr. Doherty launched CMOHS in the early 1980s to provide oral health services for disadvantaged children and adolescents who were unable to access dental care. Through the use of high-quality portable oral health equipment, Dr. Doherty was able to bring dental care to schools, state residential programs and other sites where children were located, removing barriers to care, restoring children with untreated dental disease to optimum oral health and providing preventive services to keep children health and disease free.  Mark dedicated his entire professional career to providing access to oral health care for underserved populations, for 30 years as the Chief Dental Officer at Dorchester House Multi-Service Center in Boston and for the remainder of his career as a dental practice management consultant, sharing what he had learned about running a successful dental program with dental and executive leadership and other key stakeholders from far and wide. From 2006 to 2019, Mark was the Director of Safety Net Solutions, a program of the then-DentaQuest Institute. In this role, Mark led a highly productive and successful team of project managers and expert advisors who provided practice management consulting to over 500 dental programs across the United States. At the beginning of 2019, Mark founded D4 Practice Solutions to continue to provide these needed services to health centers and other safety net dental programs. Unfortunately, later that same year he fell ill and had to step away from the work he so loved doing. Those of us who had the joy and privilege of working with Mark will never forget his passion for the underserved, his boundless energy, his incredible work ethic, his sharp wit, his deep intellect and his voracious appetite for life. We also will long remember his penchant for practical jokes and general shenanigans that earned him the nickname “Master of Mayhem.” He was a kind, generous and supportive leader who brought out the best in others—one who led by example and demanded both excellence and accountability. Rest easy, Mark—we will miss you terribly and honor you by continuing to carry out the work that meant so much to you.
