James Jernberg


Owner and Head Coach

James is a proud husband to his redhead Chelsey and an overjoyed Papa to his stout and dimpled Oslo. For him, family is everything, and that mindset was the basis of his desire to open a welcoming space where everyone felt like family, more specifically, the Fiternal Family.

James has 15+ years of experience in the health and fitness industry. He is a proud University of Wisconsin – Stevens Point alum and former Pointer hockey player. He’s also traveled the world as an International hockey player and continues to play on a weekly basis. An avid outdoorsman, James enjoys hunting and fishing.
