Tom and Kat are also the founders of OneCaliforniaBank, an Oakland, California community development bank now called One PacificCoast Bank. Tom recently teamed with George Schultz, former Secretary of the Treasury and Secretary of State, to defeat California's Proposition 23, which would have rolled back new state environmental laws.
