Meet Stefanie Warren

Stefanie helps businesses navigate California’s complex regulatory structures and manage the associated compliance burdens and liability risks so each client can focus on their business. Stefanie also counsels and negotiates for clients who are the target of federal and state government investigations and other private enforcement activity and litigates to resolve cases in court and before administrative tribunals.
