Leslie Pellerin (Seeley) was born in Oshawa in 1963 and remained true to her hometown roots beginning an exceptional four-year collegiate career at Durham College in 1982. Prior to graduating in 1986 she was named an OCAA all-star for fastball in the 1984-85 season, volleyball in 1985-86 and basketball three times between 1982-83 to 1984-85 establishing herself as a rare three-sport athlete.

In all, she won a Durham College record 11 championship medals, including eight gold, one silver and two bronze. As a standout infielder and point guard she helped the Lords to three consecutive OCAA championships in fastball from 1982 to 1985 and back-to-back OCAA championships in Division II basketball in 1982-83 and 1983-84. Her successes continued with her selection as Female Athlete of the Year in 1984-85 and culminated as a valuable member of the Lady Lords volleyball team that won the Ontario championship before earning bronze at the CCAA nationals in 1985-86.

Before her graduation, Leslie became the all-time career scoring leader in Division II women's basketball and in 1997 was inducted into the Durham College Sports Hall of Fame.
