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 from Fairleigh Dickinson University where his interest in medicine 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, tightening his links to chemistry again. He has been an active participant at NACCT meetings since 1993.

In his previous position at the Maine Medical Center from 1195-2006 Dr. Tomassoni contributed to the growth and certification of the collaborative Northern New England Poison Center which he served as Medical Director. At MMC, Tony also created a popular med student and multi-specialty resident rotation in Clinical Toxicology. He has been an item writer for the certification exam for Specialists in Poison Information since 2000, and is the outgoing Chair of the AAPCC Medical Director’s Committee. Tony enthusiastically supports the training and practice of non-physician toxicologists as an adjunct Senior Scientist for the Wise Laboratory of Environmental and Genetic Toxicology at the University of Southern Maine.

Through the Yale New Haven Health System he serves as Medical Director of the Yale Office of Emergency Preparedness (OEP). Tony’s early 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 chapters in 3 toxicology texts and 2 electronic references. In addition he was the recipient of the 2008 Faculty Teaching Award from the graduation EM residents.

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, the Northern New England Metropolitan Medical Response Systems Steering Committee, Emergency Medicine at Yale, as Senior Leadership at the Yale New Haven - Center for Emergency Preparedness and Disaster Response, and most recently with the American Association of Poison Control Centers. Tony’s most exciting current project entails developing a proposal for the creation of a sustainable model medical response system to include toxicology and HazMat components for a developing nation. After work Tony spends free time outdoors and raises bees and award-winning German Wirehair Pointers.
