Randy Philipp, Ph.D.

Bio

Randy grew up in the San Fernando Valley in California, where I earned a degree in mathematics and then a fifth year single-subject teaching credential in mathematics. I worked my way through college "busting tires" at Sears, and in my spare time I taught CPR courses for the American National Red Cross and I served as a Big Brother of Greater Los Angeles. I spent the next two years as a Peace Corps Volunteer teaching mathematics at a junior high school and in a teacher training institute in Liberia, West Africa, where, while out for a run one afternoon in the bush, I decided I enjoyed working with prospective teachers even though I did not know what I was doing. I decided then to pursue a graduate degree in mathematics education. I returned to the U.S. and taught mathematics in an inner-city Los Angeles high school and then in Canyon Country, north of Los Angeles. While teaching, I worked on an M.S. degree in mathematics at night and I also served on a crisis intervention help-line. Upon finishing my M.S. degree, I married, moved to Wisconsin, and studied for my doctorate under the direction of Tom Carpenter.
