Just to echo what Kyle previously mentioned... Joe Machnik's No. 1 Goalkeeper Camp is likely the best thing you could do for your son. While this camp is a bit spendy (about $700), it is well worth the investment. Your son is at a perfect age to take advantage of this type of training. He will return home (after a full week of training 3 times daily) in awesome shape, confident, and ready to take on the goalkeeping world!
As a high school goalkeeper coach, I encourage my players to attend this camp!
The next step is finding somebody local who can continue to reinforce the techniques learned at camp!
Here is Machnik's homepage:

Best luck!
