Hansa Jacob-Martin: Administrative Manager

Hansa moved to the Bay Area in 2014 from Washington, D.C. where she first took up bicycling while living in Capitol Hill to explore the District. She believes she is exceptionally fortunate to be a part of the Bike East Bay family. Growing up in India she had seen large numbers of people for whom cycling was a sole means of transportation and how bicyclists kept the streets safer, calmer. She finds it exciting to learn that way of life is a reality for many and a possibility for many more in the East Bay area.

Eager to support bike advocacy and education she brings her experience in Accounting and Human Resources from Texas and the East Coast to work part time at Bike East Bay. Hansa has an accounting degree from University of Texas – Arlington and a Masters in Organization Development from the School of Public Affairs, American University, Washington, D.C.
