As a teenager, Tyler Merren was diagnosed with retinitis pigmentosa, a degenerative eye disease which causes gradual deterioration in sight. He was introduced to goalball in 1999 at a sports education camp hosted by U.S. Association of Blind Athletes at Western Michigan University. He is now a 5X Paralympian, with one silver and one bronze medal, in the sport. Tyler recently retired from Team USA, but still plays in Grand Rapids for a team sponsored by Mary Free Bed, a Move United member organization. Tyler also works as a personal trainer, motivational speaker and founder of ReVision Training LLC.
