I'm climbing into a vehicle that has a powerful influence on our culture. I'd like to make it do something good.

We start with people who are motivated to get paid and be on TV, and we end up with people who have been transformed by the experience and go on to embrace sobriety. If they relapse, like most of my patients do, we continue to support and treat them.
