Not sure where exactly you are in CO, and I am not from there, but have really good things about FAST arm care in Denver. I believe one of their players/trainers is Peter Bayer who is in the minors and has trained at driveline in the past. I also believe Jason Hirsh is the owner. Obviously take this with a grain of salt as I have not been there myself, but it may be an interesting place to at least check out
