David J Walker

Owner & Head Coach

U.S. Navy veteran and Lodestar's founder, still coaching classes every week.

More about David

David founded Lodestar Fitness in November 2018 after nine years as a U.S. Navy helicopter pilot, a walk-on spot on Florida State University's 1996 national-championship football team, and a psychology degree that still shapes how he coaches today.

He holds a Certified Level 2 Coach credential and a Masters Coaching credential, and previously worked as a high school strength & conditioning coach.

He still coaches classes every week: this is a gym he built to run, not one he built to step away from.
