We are honored to work with these amazing organizations! 


We raise all of our grass-fed Angus/Hereford beef in Petaluma. Our cattle are 100% pasture-raised, grass-fed, and grass finished. We introduce new breeding stock from local breeders to avoid inbreeding and to support other local ranches. We do not offer grain finished animals. 


SoMar Farms is located on the border between Sonoma and Marin counties (hence our name SoMar) in the agricultural area of West Petaluma.

our ranch:

We control thistle by pulling, mowing, and good grass management. Our creeks are fenced and planted with willows to reduce erosion and keep nutrients (cow manure) out of creeks. The ranch is cross fenced to maximize grass production and we use solar pumps to move water around to each pasture. 


Our mission is to raise delicious beef in an environmentally responsible and humane manner.

our lamb:

We have also started raising grass-fed Lamb. Like our cattle, the lambs are 100% pasture raised, grass fed and grass finished. None of our animals are ever treated with hormones. The lambs are moved around the ranch using a portable fence so we can control where and how long they are grazing each area.
