McMahon will be co-head coach alongside her husband Justin Serpone and says the World Cup is another stepping stone to helping lacrosse become an Olympic sport.
"The idea of bringing a sport that we are both passionate about to a country that is passionate about everything they do, is just a great fit on both sides," continued McMahon. "I believe I can speak for most coaches out there when I say it's a unified goal of ours for lacrosse to become an Olympic sport, so whatever we can do to help that become a reality, we are willing to do pretty much anything."
