Keith Rust teaches Graphic Design, at least for Period 1. I'm pretty sure there's other teachers for periods 3 and 5 but I could be wrong.

"Hello Wildcats!

I grew up on my family’s ranch in Northern California, and am a 5th generation Californian. Beginning at an early age I was always creating, but it was my first art professor in Sacramento, John Kaneko, who became a true mentor and friend. With my instructor’s recommendation, I decided to attend college at Art Center College of Design to study illustration. After graduating with honors, I began working in the computer game industry, starting off as a game artist and eventually rising to the position of Art Director and Vice President of Creative Arts. I thrived in the computer game industry for over a decade before my interests shifted to a new career path. After taking some time to travel, I transitioned to a high school art instructor, teaching traditional drawing and painting as well as graphic design. During my time at Art Center, I was exposed to the incredible craftsmanship and esthetic beauty of the Arts & Crafts movement surrounding me in Pasadena, and quickly fell in love with its beauty and style. I have always had a great passion for the outdoors, photography and art and spent several years developing a new style of painting that pays homage to the Arts & Crafts movement through the inspiring beauty of the great outdoors."
