The acquisition includes six NorthWest Insurance operations in Santa Rosa, Napa, Ukiah, Gualala, Fort Bragg and Eureka. Other terms of the acquisition were not disclosed.
NorthWest's operations in Crescent City and Grants Pass, Ore., were not part of the acquisition and were sold to another agency.
Nearly all NorthWest employees will be absorbed into George Petersen, and will remain in their current positions. Staff members in Santa Rosa and Eureka eventually will be consolidated into single, larger offices in each city.
