The Baseball Performance Academy

BPA was founded on the premise of providing an opportunity of top instruction, for players that have a desire to play the game beyond a recreational level.

Our purpose is to ensure players learn to play the game the right way and compete at the highest level. We aspire to positively influence a player’s next-level opportunity by providing them with the knowledge and skills required to play the game to the maximum of their potential.


Seeing someone miss an opportunity in their life, especially when its something they have so much passion and desire to be great at, in our eyes, is a travesty. Preventing this from happening to our players, and continuing to push of program alumni, beyond  where they ever could of dreamed of playing is why we do what we do.

Through high-paced, intense and individualized instruction, BPA focuses on the physical and mental details of baseball with an emphasis on accountability.

We believe optimal learning environments occurs when one is placed out of their comfort zone, and operating at the edge of their ability. Our highest priority is to at all times create an environment of care, transparency and concentrated discomfort, to make sure a player has the opportunity to maximize their potential.

BPA brings together baseball minds with a proven track record of performing at a high-level, as well as bringing a teacher's mentality to ensure we help maximize the potential of every player, regardless of age, skill and desired goals.
