20 YEARS OF INNOVATION

CEO and 3-time Team USA Paralympian William Hernandez starting building his own chairs in 1999 as a student-athlete studying engineering at University of Texas – Arlington.

He believed in a better way to build a better performance wheelchair for himself and his teammates.

MADE IN THE USA
