Founded in 2007 by Marine Corps veteran Steve Danyluk, the Independence Fund's Trackchair program has aided over 2,700 wounded veterans

More than 2,700 all-terrain Track Chairs were delivered to double, triple and quadruple amputees, the Independence Fund has said. The initiative gave freedom back to wounded veterans of Iraq, Afghanistan and even Vietnam, allowing them to hunt, fish and go off-road with their families.

Specialized all-terrain trackchairs are engineered to navigate challenging terrain including, snow, mud, and dirt, these mobility devices enable Veterans to reenter the outdoors and engage in the activities they enjoy.
