Matthew returns to The Doctors after turning his life around following a cancer battle, the loss of his legs to heroin, and successfully conquering his substance abuse struggles. He shares he's now advocating for other amputees.

He joins the show with his girlfriend Wendy, who he met at a Hanger Clinic event, and they connected over a mutual interest in the outdoors and winter sports. Matthew is now sharing his love of sports with other amputees, and he now offers support, inspiration, and guidance as a certified peer visitor.

He says after appearing on The Doctors and getting our help, he felt "revived." "It was like a light switch was turned on," he says of his new involvement in competitive sports like running, swimming, volleyball, and even a triathlon.

"I couldn't have done it without The Doctors' support and the support of my family. Thank you guys for everything," Matthew tells us.
