Before coming to La Verne in 1976, Dr. Clark taught at the University of California, Berkeley, and at Pomona College while he was completing his dissertation in Late Modern European History. After two years as Director of ULV's Naples and Sigonella (Italy) Centers and another as Director of the University's Athens Center, he became Assistant Dean of Academic Affairs in 1983. While steadily progressing from that post to his current rank, he oversaw La Verne's international student affairs, study abroad, and Weekend Series, and he founded La Verne Online. Currently, he is responsible for Quality Management, the University Catalog, and relations with WASC. He participates in several committees including Educational Effectiveness and Faculty Research. He organizes the annual Faculty Lecture Series, Faculty Research Day, Faculty Book Day, and the Part-Time Faculty Workshop. He also helped create La Verne Academy into which he was inducted as an honorary member in 2009.

Dr. Clark teaches in the Honors Program, CAPA, and ULV Online, most notably Humanities 313 and Honors 370. He is sponsor to the Alpha Chi and Alpha Lambda Delta National Honor Socities at La Verne and sits on the National Council of Alpha Chi as the Secretary-Treasurer for Region VII. He published Citrus Speaks in 1994 and is in the late stages of research for a historical and environmental book on the San Gabriel Watershed.

An important side benefit for him of teaching HUM 313 and HONR 370 is going to the theater or visiting a museum on average once a week. He also enjoys reading, gardening, and jogging. ULV's Rideshare program motivates him to bicycle to and from work seven days a week.
