Previously, R.J. earned his B.A. in English from the University of California, Irvine and his M.A. in the same subject from The Ohio State University. In his spare time, he loves watching movies (with a particular fondness for Classic Hollywood and silent comedies), reading (his interests run the gamut from William Shakespeare to Jane Austen to contemporary comic books), playing board games, and looking for new and interesting subjects to learn about.
Lorelei Atkins
Customer Service Specialist
Lorelei has an AA degree in graphic design and a BA in multimedia focusing on web design. After college, she got a job in tech support for an E-commerce software and web hosting company where she became an engineer and spent her days either helping clients with the E-commerce platform or doing more technically oriented things like migrating data and launching sites. In her spare time, Lorelei enjoys knitting solo or with friends. She has several projects going at once, so she's generally pretty busy with that or going out to various events with friends. Occasionally, she likes to take the train or local transit for the fun of it. She calls it backpacking. She of course brings her knitting with and knits in various places, especially in places someone probably wouldn't expect to find her knitting in (like the bar). Sometimes she also plays video games like The Sims 1-4.
Vanessa Baeza-Apodaca

Aside from doing math for fun, she dabbles in hobbies including reading, crocheting, building 3D puzzles, and playing soccer.
Rodney Bills
Beast Academy Art Director
Originally from Provo, Utah, Rodney grew up spending summers in California and winters in Utah, which is odd, and probably this oddness has defined his life. From his earliest days he loved Disney animation and Disneyland. His dream was to work as a Disney animator and eventually for Walt Disney Imagineering. He was especially drawn to the work of Marc Davis, whose characters were imbued with life and story. After graduating from college with a BFA in illustration, he moved to LA where he worked as an animator, did some character design, illustrating, and creative development for games, film, educational products, Internet and mobile, eventually working with Walt Disney Imagineering on a project for the theme parks. Family needs and a great recession led him to return to his hometown where he worked creating games and interactive activities for the education industry and taught part-time at a local university. Always wanting to improve his craft, he earned a Master of Fine Arts degree in Animation and Visual Effects from the Academy of Art University. Most recently, he was able to return to his first love: animation, where he worked as an Art Director for 2D Animation at Rooster Teeth Animation in Austin Texas. His wife Jill is a special education teacher, but has spent most of their time together as a stay at home mom managing their 6 (Jill will say 7 or 10 depending on who and what you count) children.
