Meet the CleanFuel Team

Justin Cohn is the founder of CleanFuel System a performance program built to correct everything modern sports nutrition and recovery have gotten wrong. A former junior and college player, Justin went on to build and head coach Thunderbirds College Prep in Columbus, Ohio, a program known for its relentless culture and player advancement.

Under his leadership, athletes earned Tier I/II junior and NCAA opportunities, proving that the right habits off the ice create separation on it. He has also scouted at the Tier I and Tier II junior levels, giving him firsthand insight into what truly moves players to the next stage.

After years of watching talented athletes burn out from poor fueling, shallow recovery, and weak routines, Justin created CleanFuel System to fix the foundation — teaching players how to eat clean, recover deeply, and perform at their highest level, season after season.

Mark Cheremeta is the definition of mental fortitude. His path wasn’t the straight line people imagine it was the climb through every level of hockey, each one sharpening the edge he now teaches.

From grinding in Tier 3 juniors, Mark fought his way into the USHL, earned a Division I roster spot, and eventually landed in the Florida Panthers’ Development Camp proof that mindset can rewrite your ceiling. After his NCAA career, he took his game overseas to pro hockey in Belarus, testing his discipline and resilience against the pressures of elite competition.

Those years built the foundation for Top G Mindset his elite mental performance system designed to strip away fear, rewire confidence, and weaponize focus. He’s now partnered with CleanFuel System to integrate that mindset mastery directly into our athlete framework turning nutrition, recovery, and psychology into one complete formula.

Mark’s coaching goes far deeper than motivation. He teaches self-hypnosis, visualization, and performance reprogramming the same tools he used to climb from overlooked to undeniable. Every athlete who works with Mark learns how to dominate their inner game before stepping on the ice.
