Williams & Gumbiner is a law firm that practices throughout California, specializing in the following areas:


Mr. Williams is well known in the Bay Area and beyond for his representation of property owners, including businesses, common interest developments and individual home owners, in connection with claims and suits against builders and developers arising from defective construction.


For three decades, we have represented insurance policyholders (businesses, municipal entities and individuals) in all manner of insurance disputes. We are equally adept at convincing insurers to pay difficult claims and coverage disputes, as we are at litigating them in state and federal trial and appellate courts.


Floods, landslides, natural and man-made disasters do tremendous damage to homes and businesses in California. We serve our clients by seeking compensation for property damage and business interruption, without litigation if possible. Where necessary, we litigate aggressively and cost-effectively.


We have more than 30 years experience representing carriers, shippers and intermediaries in all modes of transportation: rail, motor carrier, ocean and air. We draft and review contracts, litigate breach of contract and cargo loss claims, and serve as expert mediators in these matters.
