Silicon Valley

In 1991, Weil was the first global, non-California law firm to open a Silicon Valley office. Now, more than 30 years later, we continue to be a leader in this critically-important legal market.

Pro Bono Initiatives and Community Service

Philanthropy is a cornerstone of the Silicon Valley office. Through its “Weil Gives Back” program, lawyers and staff collaborate with local charities, such as Second Harvest Food Bank, Community Legal Services in East Palo Alto, Progeria Research Foundation, Wardrobe for Opportunity, American Lung Association and the Justice & Diversity Center of the Bar Association of San Francisco, with respect to meaningful, and often life-changing, community service and pro bono legal projects.

The Silicon Valley office’s dedication to the community is evident through its history of pro bono success.  For example, Weil served as co-counsel with the Center for Constitutional Rights and others in reaching a landmark settlement in the federal class action Ashker v. Governor of California that ended indeterminate, long-term solitary confinement in all California state prisons.

Over the years, Silicon Valley lawyers have also contributed thousands of hours of pro bono service to the Legal Aid Society of San Mateo County, including a recent case involving relief for a victim of family elder abuse.
