Tessie Guillermo

TESS

Tessie Guillermo joined the Marguerite Casey Foundation Board in August 2015.  From 2002 to 2015 Ms. Guillermo was President and CEO of ZeroDivide, a social impact consulting firm that works to improve the health, economic opportunity, education and civic engagement of underserved communities through the innovative use of technology. Prior to joining ZeroDivide, Ms. Guillermo spent 15 years as CEO of the Asian & Pacific Islander American Health Forum, a leading national health policy organization. In 2000, President Bill Clinton appointed Ms. Guillermo to serve as an inaugural member of the President’s Advisory Commission on Asian Americans and Pacific Islanders.

Ms. Guillermo’s roots with ZeroDivide, and her engagement with technology issues, predate the organization itself. She was among a group of advocates representing 144 organizations that lobbied the Public Utilities Commission to intervene in the merger between Pacific Bell and AT&T. The lobbying efforts proved successful, and the merger resulted in a fund allocated to address the digital divide over ten years. In 2008, when the work of this fund (then called the California Community Technology Foundation) was ending, Ms. Guillermo recognized that the effort to close the digital divide was not finished. To that end, she transformed the grant-making foundation into a 501(c)3 organization to continue its valuable work.

Ms. Guillermo serves on the boards of Dignity Health, the Lucille Packard Foundation for Children’s Health and the Nonprofit Finance Fund. Ms. Guillermo served on the Board of the California Endowment for ten years, the last three as Chairwoman. Ms. Guillermo, who holds a Bachelor of Arts in Economics, is an alumna of the University of California, Berkeley and California State University, East Bay.
