Our Athletes

David is an extraordinary student-athlete who exemplifies the art of balance between academics and training. A highly dedicated and decorated Brazilian Jiujitsu competitor, he trains at Proving Grounds where he pushes himself daily to improve. His relentless work ethic and passion for the sport have earned him numerous gold medals, a 2024 IBJJF Pan-American Championship, ADCC Championship, and the most active competitor at his gym. He takes great pride in his style, always competing in his Black Ice Premium Fightwear with style and comfort. David would not be where he is today without the incredible support of his father and the guidance of his coaches, particularly Jason Kaczmarek. Their mentorship, wisdom and dedication have shaped him into the fierce competitor and incredible young man he is today.
