My name is Achim "Dange" Dangerfield. I have taught Earth Science, Biology and now teach Chemistry and Video Production at B Tech Academy. Every Thursday night I also teach a "How to play Guitar Class" at Berkeley Adult School. Before I taught Science I lived and worked in Los Angeles, working in the TV/video production industry and was the guitarist of Chevy Metal, the finest dirt-rock power-trio cover-band in the world.
