About Don:

Originally from Colorado, I moved to the Bay Area in the mid 1960s as an undergraduate at the University of California, Berkeley where I earned a bachelor’s degree in English literature. I continued my education to earn a master’s degree in applied economics from the University of Hawaii as an East West Center Scholar and an MBA from Stanford University.

My business experience includes international consulting for the United Nations and the U.S. Agency for International Development in the Republic of Korea, Sri Lanka, Sierra Leone and Rome. Additionally, I was involved in an initial public offering as vice president of marketing at a biotechnology company, Escagenetics.  I also had years of contract negotiation experience, including collective bargaining and intellectual property transfers both in biotechnology and as chief operating officer for Catholic Charities of the Archdiocese of San Francisco.
