After coaching for two years in California, Bowdoin College graduate Tom McMahon returns to New England for his first season on the Wheaton coaching staff.

McMahon assisted the Pomona-Pitzer Colleges program from 2007-08, working with hitters and infielders. The squad earned the Southern California Intercollegiate Athletic Conference (SCIAC) title in 2007, qualifying for the NCAA West Regional Tournament.

For much of 2006, McMahon coached with the Belgium-based Brussels Kangaroos baseball club, heading four teams with players ranging in ages from 6 to 30. In addition to coaching the squad, he played for a team that went 22-2 and won the national championship. McMahon also coached Belgium's national Little League team to the Trans-Atlantic Regional Tournament in Poland, and another squad he coached during the summer advanced to the Senior League World Series in Maine.

During his college career, McMahon was a senior captain and earned New England Small College Athletic Conference (NESCAC) all-league first-team honors as a junior. He graduated among the top five in program history in career home runs, runs batted in and slugging percentage, and the five saves he had as a senior put him third in a season at Bowdoin. McMahon was also a reserve quarterback for three years on the Polar Bears' football team.

A 2005 college graduate, McMahon earned a degree from Bowdoin in government and legal studies. He is working toward his initial licensure of education from the Massachusetts Department of Education at Bridgewater State College.
