InterWest Insurance Services was founded in 1992 as a result of the merger of three large successful insurance brokerage firms located in Northern California. Our aggressive marketing and acquisition efforts have extended our influence into Central California and the San Francisco Bay Area. During the past 25 years, we have successfully unified into a single seamlessly integrated organization with 12 offices throughout the state. We’ve grown in size from $10 Million in annual revenue in 1992 to over $70 Million.
