Guilbault, a native of Pointe Claire, Quebec, was tabbed by AIAW All-American in 1981 after leading the Lady Seminoles to five team titles, including the AIAW National Championship. Guilbault also took individual titles in the prestigious Dick McGuire Invitational in Albuquerque, N.M., and the Lady Paladin Invitational in Greenville, S.C., during her junior season. She tied the tournament record of 218 at the Dick McGuire and set a new Lady Paladin Invitational tournament record of 214. The record eclipsed the previous low held by professional golfers Nancy Lopez and Betsy King. While playing in the Lady Paladin, Guilbault also tied a course record with a round of 69.
As a sophomore in 1980, Guilbault captured three individual titles including the Tribe-Auburn, Beacon Woods and Peggy Kirk Bell. She was named the team's Most Valuable Player for her efforts. A back injury during her senior season cut Guilbault's remarkable collegiate career short.
After a brief period of time off from school in an effort to rehabilitate the back injury, Guilbault returned to Florida State in 1984 to finish her bachelor's degree in physical education. She went on to play on the Futures Professional Golf Tour and in the 1990 U.S. Open at the Athletic Club in Atlanta.
