"As a person I value the way you work when someone isn't looking, it shows more about your character than anything else. I would rather have 9 bulldog average players than 9 all-star talented players with no "dawg" in them. I will do my best to get the most out of each and every player I have the opportunity to work with. I'll help our clients on all phases of the game, while also teaching them how to lead. You will see improvements on how you go about your business in everyday life."- Aaron Schnurbusch
