I have never been so inspired to recommend anything or anyone via web before. Back a couple years ago i received Tommy John surgery from the prominently known Dr. James Andrews in Birmingham, Alabama. I had to go through rigorous physical therapy at MIHP in Warren, Michigan. [http://www.mihp.net/]
I was amazed at the expertise and knowledge they had on assessing my injury and i recovered ahead of schedule, eventually coming out a stronger and faster pitcher!
If you are looking to improve your pitching mechanics and increase your velocity (Metro-Detroit area), then I highly recommend MIHP services.
Right now they are doing a study and if your interested in receiving a free bio mechanical assessment check out the link!
