Dr. Franzos is a former Navy pilot turned physician with board certification in both Cardiovascular Disease and Internal Medicine, plus additional training in Aerospace Medicine. He is an Associate Professor of Medicine at the Uniformed Services University (USU) School of Medicine. Originally from Pittsburgh, Pennsylvania, Dr. Franzos completed medical school at USU, then residency and fellowship at the National Naval Medical Center (NNMC) in Bethesda, Maryland (renamed the Walter Reed National Military Medical Center). Recently retired from the Navy at the rank of Captain, Dr. Franzos served in many leadership roles, including Chief Medical Officer at the Pentagon’s multi-specialty clinic and Chief of Medicine at NNMC. He concluded his military career at the U.S. Navy Bureau of Medicine and Surgery as the Deputy Chief Operations Officer and Director of Force Medical Readiness. Dr. Franzos transformed Military Medicine through policies that established medical readiness as a core contributor to unit effectiveness; used evidence-based data to improve medical evaluations for accession, retention, and disability; authored guidance on post-COVID-19 return to exercise and deployability; and focused on preventing exercise-related collapse. As an Associate Professor, Dr. Franzos is currently engaged in clinical care, teaching, and research, particularly interested in using artificial intelligence in cardiovascular diagnostics, leadership principles, and pre-participation examinations for competitive athletics and military service.
