TEAM TRAINING
At Grand Slam Training we want to support all teams that may be in need of a indoor training facility. Baseball and Softball teams are welcome to rent cages or the open indoor field to get some extra reps in no matter the reason. 
OPEN TO PUBLIC
Are you a parent that would like to get your child some extra reps in the batting cage or help get extra soft toss reps in?  Coaches and parents are welcome to bring their players or teams and rent out any portion of our facility by the hour. Just call and book a time slot.
SELECT TEAMS
We call ourselves the Dawgs and we are currently building out our Select Team Program with teams in the baseball 13U, 14U, 15U and 16U age brackets already playing in tournaments. If you have an athlete looking to step up their game or switch to another program for any reason, you may have a Dawg in your home!  Schedule a time for your athlete to show us their stuff!
PRIVATE LESSONS
We pride ourselves with staffing our facility with coaches that once played. They know the game, understand the delicate journey of a player/coach relationship and have actually experienced the ups and downs of being an athlete. Many of our coaches offer their time outside of coaching teams to provide private lessons to athletes looking to enhance their skills. Lessons start at $60 per hour or we have packages available for those players really wanting to take their game to the next level.
