I'm a volunteer writer with the Atlanta Radio Theatre Company (ARTC). They've been around since 1984 and they're dedicated to creating quality audio drama and teaching others how to do so as well. I met them through DragonCon and they're some of the best people I've had the privilege to work with. I feel like I've found my tribe with them.
Here are links to preview some of the scripts I've written with them:

I got into Radio Drama by finding the show Cabin Pressure by John Finnemore on Audible.com. I haven't been addicted to a show like this since I was six years old. I just keep re-listening to it. It's comedic tale of growth and hope is just as marvelous as it was the first time.
