Heatherhendrix, welcome to the HSBBW! It's good that you've found the HSBBW while your son is 10. The "camps" that you speak of NCAA and Pro Day are by the same company. I can't speak to their reputation but generally speaking "camps" are not a necessary step for a young player to reach his full potential. I assume their reputation is great with the list of D-1, D-II, D-III and Juco colleges on their agenda (my son's college being the first on the list when you click on the link)
NCAA Baseball Camps I want to venture away from your specific question and speak more in generalities.
It would be easy to say "Your son is only 10, forget the camp and let him play and enjoy the game." But I feel compelled to say more.
Bottom line baseball is a game and everything revolves around "the game". The ultimate experience your son can have is playing the game to the best of his ability. First you want to find him a good team (I'm sure you've already done that.) Next you want to improve his skills which allows him to play the game at the highest level he can. This will multiply his satisfaction, confidence, and appreciation for the game 10 fold. No doubt in my mind that a player his age needs specific instruction in hitting, fielding, and pitching (even tho he may never pitch). The private instructor is by far the best way to go to get that specific instructions. The money you would spend on 1 camp would buy some great private instructions.
Back to camps: Personally I look at camps as more of a positive feel good baseball "experience" instead of an cost effective way to get better. As your son gets older the "exposure" aspect of his game enters in. He will need to be seen by coaches in order to get to the next level. Things will surely change from today's methods by the time your son needs exposure so hang in there, WELCOME, join in, and keep us posted.
