Process service in Sonoma County

Sonoma County blends wine country, coastal towns and the growing city of Santa Rosa. Wineries, hospitality businesses and agriculture generate business disputes, while recent wildfire rebuilding has added property, insurance and construction cases.

Properties range from downtown apartments to hillside vineyards and rural coastal homes, so each assignment is planned around access.

We serve papers anywhere in Sonoma County, including Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg and Sonoma. Every assignment is completed by a California registered process server, with GPS-stamped attempts and a signed proof of service you can file.
