The all-time winningest coach in program history, Parcelluzzi has compiled an outstanding record of 158-75, a .678 winning percentage in addition to boasting a conference mark that is even higher at .813 capturing 91 of 122 league contests (91-31). She has led the Red Hawks to seven conference championships, six NCAA Division III Tournament appearances and has coached all seven of Montclair States All-American selections.

During her time, Parcelluzzis squads have won no fewer than nine games in a season and registered 12 or more wins nine times including three 15-win campaigns.

Taking over the team in July 2005, all Parcelluzzi did was guide MSU to a 15-3 mark, setting the season record for victories. The Red Hawks won their final 12 games of the year - another record and their .833 winning percentage was one of the best in Division III. In addition, Montclair posted a perfect ledger during the regular season in the Skyline Conference and remained that way as it captured its first league title by outscoring its opponents, 40-11 in the Skyline Tournament. The Red Hawks then put the exclamation point on its banner season by winning the ECAC Division III Upstate Championship in just its second postseason appearance. In addition to its team success, Montclair also had eight players named All-Conference and four chosen to the IWLCA Boardwalk All-Region Team. For her efforts, Parcelluzzi and her assistants were named the Skyline Conferences Coaching Staff of the Year.

Parcelluzzi followed up her sensational first season with an even better one in 2007. For the second consecutive year MSU dominated its Skyline and claimed the conference title. This time, the league crown came with an automatic bid and put the Red Hawks into the NCAA Division III Womens Lacrosse Championship for the first time where they made the most of it topping Eastern Connecticut in the first round before falling to Hamilton College in the second round. The Red Hawks finished the year at 14-4 and produced the first two All-Americans in program history in Brianna Gillin and Dina Morrone.

Montclair State would earn a third Skyline Conference championship in 2008 and claimed four the next five while compiling an overall mark of 71-41 along with an impressive 43-3 in league contests. The Red Hawks made four straight trips to the NCAA Tournament from 2010-13.
