MY COACHING STYLE
DIRECT, INTENTIONAL, INDIVIDUALIZED.
I coach athletes the way I wish I was coachedwith clarity, purpose, and respect for who they are as individuals. I don't overcomplicate things. I give simple, science-backed answers to their problems so they can focus on being the athlete they're meant to be. Every cue, drill, and progression is intentional. I teach in their language, adapt to how their body naturally moves, and build systems that fit their identity and goals. This isn't cookie-cutter training. It's about connection, accountability, and guiding athletes to help themselves. My job is to meet them where they are and give them the tools to reach where they want to go.
