InterWest Insurance Services

InterWest Insurance Services

Founded in 1992 through the merger of several independent California agencies, InterWest Insurance Services grew by consolidating regional brokerages that wanted to preserve local operating autonomy while gaining access to broader carrier relationships and back-office scale. The firm is led by a partnership group whose principal owners include Chairman and CEO Greg Van Ness, a longtime California insurance executive whose family has deep roots in the region's brokerage business. The wealth creation stems from organic agency cash flows and selective acquisitions, not from an external family fortune — making this an operator-owned professional services firm rather than a family office deploying inherited capital. InterWest places commercial property-casualty coverage across construction, agriculture, real estate, manufacturing, and healthcare — sectors endemic to the Central Valley and broader Western economy — alongside a substantial employee benefits practice that designs health, dental, and retirement plans for mid-market employers. The firm operates as a traditional independent brokerage, earning commission and fee-based revenue from carrier placements rather than deploying balance-sheet capital into equity or debt investments. Its geographic footprint concentrates on California, Nevada, and the Pacific Northwest, with branch offices in Fresno, Chico, and Redding that mirror the agricultural and industrial corridors those markets serve. Unlike the private-equity-backed brokerage platforms consolidating the industry, InterWest has maintained a partnership ownership structure where practice leaders hold significant equity stakes tied to their local books of business. The firm reports over 1,200 employees across more than 20 offices, placing it among the 30 largest independent brokerages nationally by headcount before filtering for private ownership. Adjacent capabilities include a surety bond practice serving heavy-construction contractors and a private-client group handling high-net-worth personal lines. There is no disclosed philanthropic foundation or club vehicle — the firm's structural relationship to wealth is purely operational, with partner distributions tied to annual agency profitability. In the past two years, InterWest has continued its acquisition of specialty agencies, including Sacramento-based benefits firm BenefitSource in early 2023, deepening its regional density as national consolidators bid up multiples on larger platforms. What structurally differentiates InterWest from the Acrisure-Broadstreet-Hub International cohort is the absence of a private equity sponsor dictating a five-to-seven-year exit. The partnership model means senior producers remain anchored to the firm as co-owners rather than cashing out fully and cycling into non-competes — a governance structure that lets the brokerage retain books of business that would otherwise churn post-acquisition. This makes InterWest a case study in how large-scale insurance distribution can operate without public-market or sponsor-imposed liquidity schedules, a genuine rarity at its size threshold.
