At Diadem Sports, our journey began in 2015 with a vision that transcends tennis rackets and pickleball paddles. Founded Pompano Beach, Florida—the heartbeat of the sports industry—we set out to redefine what it means to play. As the last American tennis brand, we've built our legacy on innovation. Our team, boasting over a century of combined experience as collegiate and pro players and coaches, saw beyond the status quo. We didn't just see strings and rackets; we saw untapped potential. This insight led to breakthroughs like our Solstice Power string with patented Star Core Technology, offering unparalleled spin and control.
