A private coaching gym built around people, not programs.
GN Strength was founded on the belief that lasting results come from consistent coaching, purposeful training, and genuine relationships. Every athlete and adult begins by understanding where they are today, then follows a plan designed around their goals, abilities, and stage of development.
Whether you're building confidence for your first sports season, pursuing higher levels of athletic performance, or improving your strength and health as an adult, you'll receive expert guidance, accountability, and coaching every step of the way.

Helping people become stronger, healthier, and more confident through purposeful coaching.
Helping people become stronger, healthier, and more confident through purposeful coaching.
For more than a decade, I've had the privilege of coaching athletes and adults through every stage of their journey—from first workouts to high school competition, healthier lifestyles, and even national-level success. Along the way, I've learned that great coaching is about more than writing workouts. It's about understanding the individual, building trust, and providing the guidance needed to help people continue making progress.
Today, I serve as the Strength Coach at Hackett Catholic Prep while also coaching athletes and adults at GN Strength. Every coaching membership reflects the same philosophy: understand the person first, create a purposeful plan, and provide the accountability and encouragement to help them succeed.
Whether your goal is to perform better in your sport, build strength, lose weight, or improve your long-term health, my commitment is the same—to provide expert coaching in an environment where you feel supported, challenged, and confident in the progress you're making.
