About Us

About Our Agency

Sanguinetti & Co. Insurance Brokers, Mark Twain Insurance Services has served Stockton, Lodi, Angels Camp and the surrounding Central California community since 1978. What began as a local, family-owned agency has grown into one of the region’s trusted independent insurance brokers, with offices in both Stockton and Angels Camp.

Owner and President Karen Sanguinetti leads a team of licensed agents who specialize in personal insurance, business insurance, farm and crop coverage, health and Medicare plans, and surety bonds. Because we are an independent agency, we aren’t limited to one insurance company. We shop top-rated national and regional carriers, including Nationwide, Liberty Mutual, Progressive and Mercury Insurance, to build a policy around your needs and budget rather than fitting you into a one-size-fits-all plan.

Our team takes a one-on-one approach with every client, whether you’re insuring a family home in Stockton, a fleet of vehicles for your business, or a working farm in the Central Valley. We combine nearly 50 years of local insurance experience with the personal attention of a hometown agency, so you always know the people handling your coverage.

When you work with Sanguinetti & Co. Insurance Brokers, Mark Twain Insurance Services, you get an agency that knows Central California, understands risks specific to this region such as wildfire exposure and agricultural operations, and is committed to being there when you need us most.
