"Dear Grand Slam Baseball Camp staff,Our son Alex had a great time at the June camp in Seattle! With thanks!" W. Seattle 2009


"This was the first year my son attended the camp and by the end he really enjoyed it.  He had a good time with the other kids and has continued to talk about the things he learned from the different coaches. This camp provides great values, quality coaching, and a whole lotta fun.    My son was grouped with Coach V. and Coach G. who are great!  I couldn’t have asked for a greater pair of coaches for my son.  Before camp, William played t ball, he could stop balls here and there, really couldn’t catch a ball, and would stand around not paying attention like he had better things to do.  At camp, I watched him make catches, stop line drives, pay attention, and make a few plays.  This camp is wonderful and has been a confidence builder for my son.   Thank you to the staff and a huge thanks to Coach V. and Coach G.,  Willie will be back next year." J.B. 2009 Puyallup South Hill
