My 13 year old daughter started treatment with David at the Kleven Institute after a softball injury to her right arm. David was great from the first time we met him. During her initial evaluation he grabbed a ball and glove so the two of them could throw the ball around which would help him determine how she got her injury. Not only did he come up with an excellent treatment plan for her but he also worked with her on her throwing mechanics to help prevent future injuries. I highly recommend the Kleven Institute if you want excellent and efficient treatment. She was back throwing pain free after just a couple weeks!
