WHAT PLAYERS SAY
ALEX HUSSEY
William Jessup College
I first met Andre when I was 15 and trained with him almost every day for four years. If you put in the time and effort and do what he tells you to do, the sky is the limit. I was the smallest and weakest player with little talent. Andre gave me the tools from a professional perspective that allowed me to develop a division 1 caliber skill set. His meticulous nature will assure progression in all areas of baseball, if you want it. He will give you every tool, you just have to meet him half way.​
GREG FUCHS
Oregon State University
It has been an honor to have been coached by Andre. Andre is one of the best outfield/hitting coaches and he knows the game better than anyone. He is extremely talented with his ability to develop young men into great baseball players. Andre has helped me a lot with not only my out-fielding but also my swing. He is a great man and really cares about every person he coaches. His passion for the game is unbeatable. I'm truly blessed to have him as one of my mentors in my life.

Over the course of a few lessons, Andre helped me find power and consistency in my swing that I had not developed in my two years playing division 1 college baseball.
