Farm History

Loren Poncia’s great-grandfather Angelo immigrated to California from Italy in 1897 and began raising dairy cows, pigs, and chickens in Marin, home of Stemple Creek Ranch. The Poncias farmed dairy cattle until 1989, when they transitioned to beef. Loren and his wife, Lisa, now raise Angus cattle and Dorset and Shropshire lamb in Marin, Mendocino, and Humboldt counties.

Stemple Creek’s livestock are born in the fields and raised in open pasture throughout their lives, without artificial hormones, growth promotants, or antibiotics. All animals are grass fed and grass finished, with no supplemental corn, soy, or grain. Hay is harvested from their certified organic pastures in the spring to save for times when green grass is scarce. The Poncias strive to steward their land in harmony with nature by practicing sound rotational grazing, feeding the soil, and restoring riparian habitat.
