Looking for pitching help near Murfreesboro TN

I live near Murfreesboro TN and I am looking for someone to work with my 13 year old on his pitching. He loves to pitch, he throws prefers to throw fastballs and change-ups he would like to expand his options and I would like him to work on his mechanics. He has two very different stances when he is preparing to pitch and one usually delivers a strike the other just looks goofy and is usually wild, but he seems to think it is more natural for him. I don’t want to fight the natural mechanics of his body so we need some help. If anyone knows someone with good references I would appreciate it!

Thanks

It appears there is an NPA-certified instructor in your town. Look here

I will definately look into wether he is a trainer or a coach! I appreciate it very much.
