Coach Bill Peterson

If you have an arm injury or pain from pitching, I can help. No pain and great gains are possible for any pitcher, at any level. Let me show you how.

I'm not a normal baseball coach. In a quest for ultimate fastballs I fell in love with an idea: could we develop high level pitchers without wrecking elbows and shoulders?

Through more than 30,000 hours of personal, experimental biomechanics research with pitchers, I've made discoveries that can eliminate the vast majority of elbow and shoulder injuries in baseball today. These discoveries also make it possible to get stronger by throwing more, instead of tearing down the arm.

By altering technique (changing how you use the arm and body) it's possible for you to stay healthy. In addition to being less stressful on the arm, let me show you how it's possible to throw harder than ever.

Along this journey I've had seven students selected in the MLB Draft, and my guys have thrown for over 30 colleges and universities, with ZERO structural injuries over the past 15 years.

My mission is simple: I want to transform baseball's culture by helping players, parents, coaches, and organizations learn how to avoid pitching and throwing injuries.
