Oklahoma Throwing Athlete Association (OTAA)

The Oklahoma Throwing Athlete Association (OTAA) is a nonprofit organization that was founded in 2021 by Dr. Clayton Nelson, an orthopedic surgeon and fellowship trained upper extremity specialist.

Our mission is to provide a comprehensive resource for players, coaches, trainers, clinicians and parents for information regarding injuries in the throwing athlete. We aim to educate, prevent and treat common throwing injuries such as shoulder and elbow problems.

Our team consists of experts from various fields related to throwing sports, such as orthopedic surgery, physical therapy, athletic training, sports medicine and coaching. We offer seminars, workshops, webinars and online courses on topics such as throwing mechanics, injury prevention, diagnosis, treatment and rehabilitation. We also collaborate with local schools, colleges and clubs to promote safe and healthy throwing practices.

Our vision is to be the leading authority on throwing injuries in Oklahoma and beyond. We hope to help throwing athletes of all ages and levels achieve their goals and enjoy their sport without compromising their health and well-being.
