Growing up in a Christian home, Matt's parents have provided a positive model for faith and ministry since he was young. Matt's faith strengthened in high school from his involvement with youth group activities as well as coaches who spent time building his character as a man of God.  He discovered FCA in college through a campus huddle and has since served as a huddle leader, character coach and board member.  Matt desires to equip athletes, coaches, volunteer, and staff so that they can impact lives for Christ wherever they go!

Matt attended Mount Union College, graduating in 2007 with a degree in Sport Management.  He played on two Football Division III National Championship teams in 2005 and 2006 as defensive back and special teams.  Matt still loves to play many sports and enjoys staying active.  He and his wife Allison live in Leesburg and like to spend as much time as possible outdoors with their dog or biking the W&OD Trail

She grew up in Loudoun County, attending Broad Run High School before earning a degree in mathematics at the College of William and Mary. One of Christina's favorite college experiences was being part of the FCA ministry on campus for four years. 

After graduating, Christina returned home to Loudoun where she taught math for eight years at Potomac Falls High School.
