Beizer started all 20 games last year but shared the goalkeeping duties with Susan Starr. Beizer was second in the Ivy League in goals against average (0.75), fourth in save percentage (.780) and sixth in saves (32). Because of an injury to Starr, she played all 90 minutes and did not allow a goal in Yale's Ivy title clinching victory over Brown and the NCAA College Cup first round win over Central Connecticut. Against Notre Dame in the third round of the College Cup, she made a season-high five saves in 45 minutes. As a sophomore Beizer was a part of two shutouts, including earning a victory by making two saves in the second half of a 3-0 win over Manhattan. As a freshman, she earned her first career win against Sacred Heart when she made two saves. Against both Quinnipiac and Fairfield she came on in relief and did not allow a goal. Beizer was a three-time all-league and two-time all-metro selection at the Maret School. She also played for the Bethesda Dragons Club team with current teammate Christina Huang. Bethesda was the WAGS Cup champion in 1999 and was the WAGS Cup finalist in 2000 and 2001. In addition, Beizer led her team to Region I championships in 2000 and 2003 and a No. 4 national ranking. Beizer also played basketball and softball at the Maret School.
