My name is Alex Greenshields and I currently live in Ontario, OR, although I spent many years living in PDX and New York City as well. I was a regular GM in the Pathfinder Society NYC group, and started a similar group here in Portland. I retired in March 2014 as the Venture-Captain for Portland, OR.
I've written a few things for Paizo. You can take a look the list here.
I occasionally tweet under my personal account, @brandingopp, or via the official @PathfinderWiki account. I occasionally post on the Paizo boards under the name "Branding Opportunity". If you need to reach me directly you can leave a message on my Talk Page or via chat through Gliph Me.
You can find me over at PathfinderWiki under the same name.
