TESTIMONIALS
Siempre estuvo ahí ayudándome día tras día y empujándome a ser mejor. Esos retos en los bullpen yo sé que eran para hacerme mejor pitcher: cada drill, cada palabra y cada consejo.You were always there helping me day after day and pushing me to get better. I know those bullpen challenges were to make me a better pitcher: every drill, every word, and every piece of advice.
He really admires you and feels like he can learn a lot from you. I’m glad we came across you and your organization.
We both see improvement, and he was very happy to get back on the mound. Thank you for your excellent coaching and patience with my son.
