Professional Instruction


My Philosophy

I started KPerformance Baseball because I wanted to bring my unique coaching style and approach to players who wanted more than the just the standardized instruction/coaching technique. I have a different approach to coaching. When my athletes fail, I teach them why they made the mistake and how to make the proper adjustments to be successful. I teach my athletes that failure is an opportunity to improve.

I believe that one of the most under taught aspects of the game is the thought process. Baseball is a mental game. It is a thinking mans game. I try to teach my athletes at an early age how to play the game from the mind of a former professional player.
