Foundation

Trev’s Role at Game Changing Performance

As Co-Founder and Head Coach of Game Changing Performance, Nathan leads the coaching systems, client experience, and program design that drive real results.

His focus is on helping everyday people lose weight, get stronger, and build a lifestyle they can maintain long-term—not just during a program.

From small group training to personal coaching, Nathan is hands-on in guiding clients through a structured approach rooted in accountability, consistency, and execution.

Philosophy: No shortcuts, no extremes.

Nathan believes the same principles that build a strong body also build a strong life—consistency, discipline, and doing the right things over time.

His coaching style is direct, simple, and focused on what actually works. The goal isn’t just transformation—it’s sustainability.

Beyond the Gym

Outside of Game Changing Performance, Nathan leads a Brotherhood Beyond Business War Room in Lake County, Illinois, where he works with local business owners to sharpen their thinking, strengthen their leadership, and build better lives across all domains.

He lives in Illinois and is passionate about helping people raise their standard—physically, mentally, and professionally.
