  • We are deeply saddened by the devastating impact of the wildfires in the Greater Los Angeles area. Our thoughts are with everyone affected, including our colleagues, alumni, clients, and friends throughout the region. We are grateful to the firefighters and first responders from LA and elsewhere for their tireless efforts to protect lives and property. With nearly 50 years of commitment to Los Angeles, we are dedicated to supporting its resilience and recovery. Our lawyers are heeding the call: assisting clients and providing pro bono legal services in partnership with a variety of local organizations as well as donating generously to support those in need. We are here to help. Together, we are strong.
