Connor Gerardo — Golf Instructor
TPI Level 1 · NASM Golf Fitness Specialist
Connor's golf journey started at a young age and has been his passion ever since. He studied Kinesiology at the University of San Francisco to deepen his understanding of the human body and how it moves through the golf swing.
From there, Connor found his way into the golf fitness industry, spending five years at Kinect Performance coaching elite high school players, D1 athletes, and touring professionals — refining his skills while learning under highly respected coaches like Alex Riggs.
With that experience, Connor developed his own movement-first coaching philosophy: helping golfers understand their swing through body mechanics and fix the movement issues causing swing faults. His goal is to make improvement simple, practical, and enjoyable — helping every golfer reach their full potential and build a lasting love for the game.
