I'd like to thank you and your team for your work with my son. Both his pitching and his running have improved by leaps and bounds. He and I are looking forward to an outstanding season with this new knowledge and practice.
Thanks again!


Coach Chris,
This is long over due. I personally would like to thank you for all that you have done for our son (James "Trey" Simmons lll). You were truly instrumental in developing Trey into the player he is today. I don't know if he would have played high school varsity baseball without the help of Extreme 24/7 over the years. You, and your assistant coaches contributed to his success as a varsity starter for North Point High School and Chaney Legion Baseball. I thank of you every time he advances to a new level in his baseball career. Thanks to your Extreme 24-7 camps he developed the fundamentals of the game, fielding, hitting, and other skills that he wasn't getting at practice. I love the humor that you have and you always have something positive to say about the ball players even when they are doing wrong. I just want to say THANKS for ALL that you have done for him. I pray that God will continue to work in you so that you can continue to give back to the community in a positive, fun, yet learning skillful way.
you are truly a special gift,
you will never be forgotten,
