In 2018, Schairer led Dean to the porogram's first-ever New England Collegiate Conference (NECC) championship and a stellar 10-4 overall record. Several student-athletes scooped up all-conference accolades under Schairer's watchful eye and he himself was named the NECC Coach of the Year. The Bulldogs went an impressive 8-2 at home, which included an impressive 20-8 win over Becker College in the conference title game.

Schairer's squad fared itself pretty well in his first campaign in 2017, going 9-6 overall which had thrilling victories over Salem State and Regis College.

Prior to his time at Dean, Schairer spent two years as an assistant coach at Endicott College as well as two years as an assistant at UMass-Lowell.

At Endicott, Schairer was the offensive coordinator, helping to lead the Gulls to a Commonwealth Coast Conference (CCC) Championship appearance while coaching two All-American attackmen. Meanwhile, with the River Hawks, Schairer helped build a brand new NCAA Division I program, working primarily on the defensive end of the field, as well as running the substitution box.

A standout student-athlete in his own right, Schairer spent one season at Quinnipiac University before transferring to Keene State where he enjoyed a stellar career. In his three years with the Owls, he earned Little East All-Conference (LEC) All-Conference honors three time, as well as All-New England and USILA North/South All-Star awards as a senior. A two-time captain and two-time team MVP, he graduated cum laude (3.60 GPA) with a degree in political science.

No stranger to Dean, Schairer's father, Steve, was the longtime men's lacrosse coach with the Bulldogs during the institution's junior college years and led Dean to an undefeated 15-0 season in 1995.
