Dan Bouweraerts
Dan runs most the grc 107 and grc 109 classes and some of the advanced illustrator class. Dan's 100 classes are ruthless when it comes to introducing you to the world of graphics. Dan has built the courses to force the students to be detailed oriented. Even though his classes are difficult, the projects he has you do are fun and entertaining.
Ron Marston
Ron is the one of the main professors for the tier two level 100 classes. Mainly grc 118, and of course he teaches some the advanced design classes. After getting use to Dan's process, taking Ron's class is like throwing a monkey wrench in your gears. He doesn't give you these huge packets of information. His project are mostly based of "it's due this date, so get it done."
Brain Wells
Brain teaches grc 110, which is one of the hardest drawing classes that you can take but the skills you learn are worth it. He also teaches grc 119, which is a class that I don't think the grc program needs anymore, but does have some fun project, but keeps you on a very tight time line. Also, Brain teaches all motion graphic classes.
