This photo was taken at Mount Sinai Hospital in New York, NY in 2000, back when Dr. Gagner worked at Mount Sinai. Dr. Gagner (center) posing with Dr. Aluiso Stoll (right) and Dr. Luís Cardona Alves, two doctors visiting from Brazil. Dr. Gagner spends much of his time teaching doctors from around the world new surgical techniques by inviting doctors to operate with him, by presenting at conferences around the world, or through live surgeries televised to large audiences.
