Tennis Lessons with Probiomechanics

Jacob is the head coach of Probiomechanics; tennis. PBM; tennis is very excited to provide tennis lessons for Pinecrest members. We hope to see you on your courts, live a more active life, and meet your physical goals.

I have always been enjoying being active and people abound with me to be more active. This trait of mine led me to pursue my bachelor’s degree in physical education and my doctorate degree in physical therapy. After all, I became a Pro in biomechanic. PBM’s practice not only focuses on learning tennis techniques but also focuses on learning fundamental movement patterns based on developmental milestones, proper body mechanics, hand-eye coordination, self-control, disciplines, and etc. I hope you found our way of teaching interesting and have fun enjoying being at the courts.
