Independent, family-owned insurance brokerage at 1001 B Ave, Suite 103, Coronado, CA 92118, serving clients since 1957 — one of the longest-established insurance agencies on the island. Crown Island Insurance operates as an independent agency, meaning agents shop across multiple carriers to find the best coverage and pricing rather than representing a single company. Services cover personal lines (home, auto, boat), small and medium business liability, commercial property, construction and contractor casualty for builders like Nicolls Design Build in the same building, restaurant and bar liability, workers' compensation, life, disability, employee benefits, and EPLI. Carriers include Travelers, Safeco, Nationwide, and others. For captive agent alternatives at the same 1001 B Ave address, Jack Dale State Farm is the only State Farm office on the island.
