Working in healthcare is iffy with a felony. You could call the TN Dept of Labor & ask if that's where he'll be looking to work. If he likes helping people there are lots of other ways to do that. He could check into non-profits that help the community & see if there's something he can do. Also check with Goodwill. I don't know exactly where you're located but here's a link to the Chattanooga Goodwill career center. There are others in the state.
