"It is my intent to improve the quality of baseball in the Treasure Valley, by instilling proper mechanics, work ethic and baseball philosophy into each ballplayer I work with."


Established in 2010, WonderBaseball offers baseball training and conditioning for ballplayers of all ages. Whether you want to introduce your child to their first sport or help your established athlete get a college scholarship, we're here to help you succeed.

We currently use the facilities at The Sandlot, Rocky Mountain H.S. and Capitol H.S. for baseball instruction.  I do strength and conditioning from my home gym.
