Get to know Golf Swing Prescription!

Founder’s Background

Golf Swing Prescription is the result of a hardworking young man and a subconscious dream buried within him. The seed was planted when his grandfather encouraged him to start caddying at the age of 13. From that moment his love for the golf game ensued and never left his heart even after college. Graduation day came and he had to make a decision; was he to follow his dream or follow the safe road? With hard work, determination and support around him, the young caddy turned his dream into a reality.  Now he helps golfers of all levels enjoy this great game more with great feedback and a simple teaching philosophy.  Click here to learn about our philosophy.
