What we broker
Work is California property and casualty insurance across three areas:
- Personal — auto, home, renters, and related household coverage for drivers, homeowners, and tenants.
- Commercial — general liability, workers’ compensation, commercial property, and other business insurance that California firms need for operations and contracts.
- Specialty — California FAIR Plan, earthquake, wildfire, and other hard-to-place property when admitted markets are limited or a policy has been non-renewed.
The service area is California, with the San Francisco office as the place of business. Independent brokers compare options; they are not a substitute for reading a policy, and coverage depends on the insurer, the form, and the risk.
Who this office helps
Typical requests include California auto quotes, homeowners and renters coverage, businesses that need general liability or workers’ compensation, and property owners dealing with wildfire exposure or FAIR Plan questions. If you are shopping a policy, start at Get a Quote. If you already have a question about a certificate, a claim, or a change, Contact is the right next step.
