Grimbeek left her mark on the women's golf program in just two years playing with the Fighting Knights (1995-97). During her time at Lynn, she posted a 79.41 career stroke average over 17 tournaments, claimed two team national championships, won two individual national championships, was a two-time All-American and was named the NGCA Division II National Player of the Year. Grimbeek wasted little time acclimating herself in her first season, recording an 80.53 scoring average in winning the NAIA Team and Individual National Championship. In the Knights first year of NCAA play she notched a stroke average of 78.35, guided Lynn to a third consecutive national crown and won her second consecutive individual title. Her 78.35 stroke average stood as a program record for nine years before being broken in 2004-05.
