Serry's career spanned over seven decades. As a proponent of Latin American music and the free-bass accordion, he performed as the featured piano accordion soloist on the radio music program "Viva América", which was broadcast live to South America under the United States Department of State's Office of the Coordinator of Inter-American Affairs' cultural diplomacy initiative for Voice of America during World War II. His performances with CBS' Pan American Orchestra and Alfredo Antonini are credited for helping to introduce Latin American music and the Mexican bolero to large audiences in the United States in the 1940s.
