McMahon was the captain of that 2015 team that posted an incredible 27-4 record under head coach Ken Toma. In the title game, McMahon, a junior, scored four goals on five shots and dished out three assists as the Pointers defeated Bonita Vista 13-6 for the Div. III title.
That year, McMahon netted 85 goals, adding 41 assists for 126 points.
The Pointers, moved up to Div. II based on their 2015 success, were defeated in the quarterfinals in 2016, but McMahon poured in 69 goals and 40 assists for 109 points.
Playing in 111 games for the Dogs between 2013-16, McMahon totaled 235 goals and 103 assists for a mind-boggling 338 points before graduation in 2017.
Toma's team has since been elevated to Div. I with the top schools in the region.
Fast forward to the recently concluded 2019 season where McMahon's Mesa College team captured the Pacific Coast Athletic Conference (PCAC) championship after recording an 18-9 regular-season record.
McMahon, who now stands 6-feet 5-inches tall and weighs 195 pounds, has become one of the Olympians' most physical and feared members.
McMahon and his teammates defeated Southwestern College 17-9 and Palomar College 11-8 to claim the PCAC crown. In the final match, McMahon starred by scoring two goals and handing out five assists to lead all scorers. The Olympians finished in third place in 2018.
During his freshman season (2018) he found the back of the net for 67 goals and added 34 assists, all in 23 games, to become Mesa's leading scorer. This year he was among the team's leading scorers with 32 goals and 27 assists in 25 games for 59 points.
