No stranger to building a new program, Pearce comes to Allegheny after serving as head coach at Frostburg State University since 2009, when the school resurrected varsity men's lacrosse after a 30-year hiatus.

A native of Chestertown, Maryland and graduate of Gettysburg College, Pearce posted an overall record of 85-62 at Frostburg, including a 67-36 mark over his final six seasons. Competing in the Capital Athletic Conference, one of the strongest Division III lacrosse leagues in the nation, the Bobcats went a combined 27-18 in CAC play dating back to the 2013 season, and qualified for the conference tournament each season between 2013-18.

A two-time CAC Coach of the Year, Pearce has coached six United States Intercollegiate Lacrosse Association (USILA) All-Americans, three USILA Scholar-Athletes, eight All-ECAC selections, 23 All-CAC selections, and 103 Academic All-CAC honorees.

In just their third season in existence, the Bobcats qualified for the CAC tournament for the first time in 2013, earning Pearce CAC Coach of the Year honors. The Bobcats repeated the feat a season later, while also advancing to the championship game of the ECAC tournament, before breaking through with a record-breaking 2015 campaign. That season, Frostburg opened the year with a 14-game winning streak and climbed to 17th in the USILA Top 20 poll, before eventually finishing with a 16-3 record. The team ranked in the top-10 nationally in scoring defense, allowing an average of just 6.1 goals per game, while they outscored their opponents by an average of 7.1 goals per game. Two players garnered USILA Honorable Mention All-America honors, while Pearce was tabbed CAC Coach of the Year for the second time in three seasons.

In 2016, Frostburg started the year 11-0, reaching as high as No. 15 in the USILA poll, and finished with a 15-4 overall record. The Bobcats scored 15 or more goals in seven different victories, while surrendering an average of just 7.3 goals per game. Once again, two Frostburg players were named USILA All-America.

Pearce began his coaching career with a four-year stint as an assistant at Gettysburg College. The Bullets won the Centennial Conference title and advanced to the NCAA playoffs in each of those four seasons, including a national runner-up finish in 2009. The Bullets were a combined 66-12 with Pearce on the staff, and were routinely ranked in the top five of the USILA poll.
