Testimonials

Cara S.
"I have never been one to produce in a clutch situation. After fouling off a few I hit one right over the shortstops head and the girl scored. Later in the game our pitcher gave up a hit with a girl on second and they scored and we were tied and ended up going into 9 innings. My pitcher was very very shaken. She said she'd been to your mental training session and before we went out we sat there and said positive statements and closed our eyes and envisioned it happening. Between each inning we told each other positive statements and we pulled through and won 2-1. I just would like to thank you for everything. That game was absolutely huge. Thank you for helping me and remembering why I love this game so much because I'd been starting to question myself in playing and it's because of the feeling after games like these."
