About your teacher
- Mr B
- I have been on the American River College mathematics faculty since 1987, where I teach most of the math classes listed in the college catalog. My degrees in math and math education come from Porterville College, Caltech, Fresno State, and UC Davis. Before becoming a full-time teacher, I worked on the staff of the California State Senate and the State Treasurer's Office.
