Buchholz's experience in coaching the GHS football team led to his instrumental role in the founding of the Florida High School Athletic Association (FHSAA), during a meeting of 29 high school principals from across the state, held at the University of Florida in Gainesville on April 9, 1920. He served as its vice president from 1920 to 1923, again from 1925 to 1929, as president of the FHSAA from 1929 to 1933, and, finally, as executive secretary (Commissioner) from 1933 to 1936. (In April 2001, Buchholz was post-humously elected to the FHSAA Hall of Fame.) He wrote the "History of Alachua County", published in 1929, and represented Alachua County in the Florida House of Representatives.
