But his influence goes far beyond the field.
Coach Trippett has consistently gone the extra mile, not only investing time and knowledge, but also personally supporting players and their families when they needed it most. A true servant-leader, he brings with him over 30 years of military service, reflecting the discipline, integrity, and commitment he models every day.
When the Spartans faced challenges after our very first practice, Coach Trippett was the first person we called, and he showed up without hesitation. That’s just who he is. His heart for football and for developing young men is unmatched.
Well-known and respected throughout the community, Coach Trippett has an extraordinary ability to connect with families and recruit dedicated coaches who share his passion. He previously coached alongside Blake and Jason at Providence, and now brings that same energy, expertise, and leadership to Cornerstone.
As he steps into his role overseeing our football program, Coach Trippett brings a clear vision: to unify our K–12 school through football, building a championship culture rooted in mentorship, discipline, and community. He sees our unique structure not as a challenge, but as a powerful opportunity where high school athletes can model excellence and leadership for younger students, starting as early as kindergarten. Coach Trippett's family also goes all in with football! He married his high school sweetheart Shelley who helps organize behind the scenes and they have two sons Michael and Jamie (who is coaching the Spartans!)
