Our expertise and independence assure the best choices for you.

Three generations of the Castle family have built Insurance by Castle from a one person business serving local community clients to a leading insurance provider in California. Today, Insurance by Castle provides a wide range of insurance services to a variety of clients, including both businesses and individuals. Our growth and success have been built on a track record of exceptional expertise, ethical professionalism, and unmatched client service.

One of the greatest benefits we bring to you is our independence. Insurance by Castle gives every client the widest possible range of insurance providers, coverages, and pricing. This means we can, literally, find the very best choice for you — our valued client. Because we are independent, we are not tied to any one insurance company. — we work for you!
