- Dubbed "The Baron," this fierce competitor was a defensive stalwart and solid overall performer for Coach Don Martin's teams of the late 1950s.
- Giersch was a junior guard/forward on the 1957-58 team that went 16-5 and earned BC's first-ever NCAA Tournament bid.
- As a sophomore, he led the Eagles in both field goals (111) and free throws (94). Giersch's accomplishments during the years that put Boston College basketball on the map are made even more impressive because of a childhood bout with polio that forced him to learn to walk again at age 7 and left one leg shorter than the other.
- He was also the baseball team's ace starter until his senior year and served in the U.S. Navy upon graduation.
- Inducted into the Boston College Varsity Club Athletic Hall of Fame in 1994.
