Game Companies?

Hi all,
I recently moved to the states (philadelphia), after working a few years in a couple of start-up game companies for the gambling industry. I worked as the lead graphic artist there - designing GUI and any other form of graphics 2D or 3D. I was wondering if anyone can refer me to a few companies in my area or any companies that create games for casinos - video slots, roulette, poker, etc. One company I found is a bit far for me to reach is wmsgaming which making pretty my what I've been doing for the past few years.
Also if anyone knows of any designers such as myself I would like to know about them as well.

Thank you.
