Chelosky was born on November 2, 1951, in
Wilmington, Delaware. He began
swimming competitively at an early age and was successful at Delaware
Amateur Athletic Union (AAU) tournaments in the early 1960s. He repeatedly won Delaware youth championships and in 1962 set the national record in the 10-and-under category for the 50-yard breaststroke, having a time of 36 seconds. He was the first person from Delaware to hold a national swimming record. Later, Chelosky attended

senior year of high school, he set records while winning all three events at the state swimming championships in 1969 and then won all four events at the state AAU championships later that year. Chelosky attended the
University of Florida and was a member of the
Florida Gators swimming and diving program. He was named an
All-American in all four seasons he competed at the school. Chelosky also competed for the United States at the
1971 Pan American Games in
Cali,
Colombia. Chelosky was married and had a daughter. He died on January 23, 2019, at the age of 67. He was posthumously selected for induction into the
