Rio Grande Underwriters was founded by Evan C. Stineman, III in 1986 as a successor to Bozarth and Breedlove Insurance Agency, which provided a standard for excellence in insurance service for 50 years.

In 2016, Evan Stineman sold the business to long-time client, Sam Sparks III. Sam is a third-generation farmer and always progressive in how he runs his operation. With his farming and business background Sam seemed like the perfect fit. Sam runs Rio Grande Underwriters, Inc. today and is passionate about it being a company that focuses on putting farmers and ranchers first.
