Anthony J. Tomassoni, M.D., M.S, FACEP, FACMT practices and teaches Emergency Medicine and Toxicology at Yale University. Dr. Tomassoni received a B.A. degree in Science Education and a M.S. in Human Biochemistry. His interest in medicine and toxicology was born from a foundation of analytical and clinical chemistry. Prior to entering medicine he taught basic sciences and computer applications to gifted students and to educators. He received his MD degree from UMDNJ – New Jersey Medical School and completed a residency in Emergency Medicine and a fellowship in Medical Toxicology at the University of Cincinnati (UC). While at UC he served as an EMS medical director and as a flight physician for 5 years. In his previous position Dr. Tomassoni contributed to the growth and certification of the collaborative Northern New England Poison Center which he served as Medical Director; while at the Maine CDC he was the architect of three Regional Resource Centers for Public Health Emergency Preparedness created to span preparedness gaps between public health, healthcare organizations and other response organizations in Maine.

Tony's current research interests focus on medical education particularly with respect to medical simulation, medical toxicology and disaster medicine. The theme that unites most of his work is injury prevention and consequences mitigation through education, planning - and when those fail - medical response. Through the Yale New Haven Health System he serves as Medical Director of the Yale Office of Emergency Preparedness (OEP). Tony’s projects with YNH-CEPDR included the drafting of diagnostic and treatment guidelines for chemical and radiological emergencies. He remains passionate about the practice of clinical toxicology and promotes the recognition of the specialty and its practitioners through frequent lectures. In addition to scientific papers and abstracts, his publications include contributions to 3 toxicology texts, 2 international EM texts and 2 electronic references. In addition he was the recipient of the 2008 Faculty Teaching Award in Emergency Medicine and the American College of Emergency Physicians National Teaching Award in 2010. He is an active member of CT DMAT-1 and past Medical Team Manager of US&R MA TF-1, both federal emergency response teams.

Tony’s most satisfying accomplishments stem from participating in the growth of individuals and programs. He values teamwork, sharing in collaborative and creative synergism to meet partners’ needs. He continues to sharpen his strategic planning and implementation skills learned in teaching and private enterprise, at the Maine Poison Center, as a member of the Medical Advisory Committee to the Maine Board of Pesticides Control, contributing to strategic planning in the Maine CDC’s Office of Public Health Emergency Preparedness where he served as the medical director, the Northern New England Metropolitan Medical Response Systems Steering Committee (and Commander of the Maine Medical Strike Team before coming to Yale), Emergency Medicine at Yale, as Senior Leadership at the Yale New Haven - Center for Emergency Preparedness and Disaster Response, and with the American Association of Poison Control Centers.
