Owner
Stephen isn’t just in the business of boxing—he’s in the business of changing lives. As Owner of Bee Relentless Boxing alongside his wife, Sam, Stephen proudly leads a family-owned gym built on passion, consistency, and community impact. “I don’t measure success by how many clients we have, but by how many lives we change,” he says—and that philosophy drives everything inside the hive.
With over a decade of experience in the boxing world, including three years as an amateur fighter, Stephen delivers an experience that goes far beyond the ring. Whether he’s coaching a workout, mentoring members, or shaping the vision of Bee Relentless with his wife, his mission remains the same: create a place where people show up, stay consistent, and become their strongest selves.
