I’ve been writing and designing in the tabletop roleplaying games industry since 1995. I haven’t included my development work here (which would extend the list even longer), just writing and design credits: I developed all Mutants & Masterminds products for Green Ronin Publishing from 2001 until 2009. I also did primary development on Blue Rose (both the True20 and AGE System editions), True20 Adventure Roleplaying, A Song of Ice & Fire Roleplaying, The Expanse, and lead design on Trinity Continuum: Aberrant.

I have written for a variety of RPG periodicals, including 40 articles for Dragon magazine and 19 installments of its “Profile” column, 50 articles for Pyramid magazine, and various pieces in Adventures Unlimited, InQuest, Polyhedron, Rolled & Told, Shadis, Star Wars Adventure Journal, Star Wars Gamer, and others.

You can find more info at the RPG.net Game-Index and a cover album on my Facebook. If you want to get in touch with me about freelance work, feel free to send me an e-mail.
