Welcome to Sonoma Mountain Herefords

Sonoma Mountain Herefords is a family-owned and operated Hereford seedstock business located in the rolling hillsides of Sonoma County, California. Our philosophy is to raise registered Hereford cattle with integrity that will work in the show ring but also function with soundness and efficiency in a commercial cattle environment. 


Through the use of new technologies in the cattle industry, we continue to move our registered program into the future. Employing ultrasound, EPD analysis, DNA testing, and AI and embryo transfer, we strive to continuously improve our cow herd, selecting for sound udders and mothering ability. Our bulls are ranch raised, never pampered, on rugged, steep hillsides where they need to get out and move in order to source their water and nutrient needs. Long yearling and 2 year old bulls are sold private treaty year around as well as a selection of females.


We are proud that Sonoma Mountain Herefords is recognized as a Gold TPR Breeder by the American Hereford Association.  Come by for a ranch tour and we’ll be happy to show you our next calf crop, our cow herd and replacement females, as well as our upcoming bulls and herd sires. We might even find time to enjoy a glass of Kunde Family wine!
