A Lancaster native, Pfrommer played football and wrestled at McCaskey High School. Upon graduation, he attended Millersville State Teachers College and wrestled in the 175-pound category under Coach Ted Rupp, where he was undefeated at 8-0. The following year, he was inducted into the Marine Corps, where he served with distinction before receiving an Honorable Discharge in 1954. After returning to Lancaster, he worked at Armstrong Cork and wrestled for the Maple Grove Athletic Club from 1954-1955 where he again turned in an undefeated record.
In 1956, Pfrommer came to F&M and in his first year wrestled "unofficially" for Coach W. Roy Phillips as a heavyweight and was undefeated in exhibition matches. Over the next three years, he was 24-2-1, one of the best records ever compiled by a heavyweight at F&M. In 1957 and 1958, Pfrommer was 4th at the EIWA Championships and in 1957, he represented the Diplomats at the NCAA Nationals.
In competition against Lehigh University-a perennial wrestling power-he had a 4-0 record. At the end of his senior year, Pfrommer earned the Uncle Charlie Mayser Award, given to the team?s most valuable player at the end of the season.
