Enter Team Valiants

Professor Jon decided to shift his focus on establishing a competition team. TEAM VALIANTS Started with only a handful of kids, to now over 30 active competitors. The family has grown! The Valiants have improved tremendously in the last few years. They went from winning individual championships to now winning team champions; All while primarily focusing on building a good character more than just athletes. Professor Jon uses Jiu-Jitsu as a tool to educate the kids in life lessons and the gospel of Jesus Christ. Jonathan’s goal is to glorify God with the skills and talents He has been blessed with.

“You are the light of the world.

A city that is set on a hill cannot be hidden.

Nor do they light a lamp and put it under a basket, but on a lampstand,

and it gives light to all who are in the house.

Let your light so shine before men, that they may see your good works

and glorify your Father in heaven.”


‭‭-Matthew‬ ‭5‬:‭14‬-‭16‬ ‭
