“I took my first Chain Reaction seminar in 2006 and my practice was immediately transformed! Even with my very basic understanding of AFS, I was able to connect better with my patients and help them achieve their goals more quickly.”

–Melissa Reh, PT, FAFS

“There's no other seminar that comes close to the quality of information found here. My mind and skills have undergone radical transformations and my clients have benefitted greatly!”

“As a former Division 1 collegiate strength and conditioning coach, previous health and wellness director, professor at a public institution, and current doctor of physical therapy…I can attest to the power of understanding the Chain Reaction Biomechanics of the human body. This training will take high level athletes, weekend warriors, and patients with varying pathologies to the next level.”
