While many other organizations teach “function,” Gray Institute is both the authentic source and foremost authority.

Gray Institute originated with Gary Gray, referred to as the “father of function.” Gary’s ability to understand Human Biomechanics and look at the body as a Chain Reaction® launched a second-to-none institute known as Gray Institute.

CAFS has not only established the "truths" of human movement in a very logical and efficient way, it has seamlessly integrated those truths with a system that gives the movement practitioner a way to simplify the complexity.  Even the practitioner that is competent in Applied Functional Science will acquire a structure to organize their knowledge base to better serve their clients and athletes.  If a person is new to Applied Functional Science, CAFS establishes a "framework" that not only allows them to organize their AFS education, but gives them the opportunity to be effective at improving the function of the individuals they work with immediately.

Every aspect of the CAFS on-line course was incredible.  It was organized on every level, from the outline to the very last video.  I wanted to applaud you all for investing the man hours into developing a well thought out system for the applied functional sciences.  I have always thought of myself as a movement professional but now this certification validates that with a formal curriculum and certification.  The information explained in the course work will be something that I will continue to develop and share with everyone I encounter.  I will gladly recommend this certification to my fellow collegiate strength and conditioning coaches that I encounter.

I truly feel the CAFS Program is a necessity in the profession of personal training. A necessity that takes the guess work out of knowing which strategy to implement for each client. Through clear understanding of the 10 essential observational elements. The personal trainer takes his or her thought process into an enhanced skill set that builds upon an injury preventive foundation of fundamental truths. Making it easy for his or her client to achieve any desired level of fitness and giving the personal trainer the recognition of being able to organically think through the process. If you are a personal trainer, and ready to operate at a higher level, I strongly encourage you to take action and realize once you become educated in the knowledge of CAFS. The shape of your professional growth will be unlimited.

I just finished the CAFS program and it is terrific! Lenny Parracino and Pat McCloskey did an awesome job of systematically communicating very practical information.

This program takes the pressure and stressors off of traditional certifications (memorizing terms/anatomy/protocols) for individuals and places more understanding on how to apply movement to enhance lives.
