About Us

Loren Mrnak is a fourth generation North Dakotan raised on a registered Hereford ranch in Bowman. At the age of five he received his first registered heifer and that was the start of his cow herd. He worked with his family through high school and summers while attending Western Dakota VoTech where he received a degree in Farm-Ranch management.

In 1986, he accepted a position with one of the top Hereford ranches in the nation, Lone Star Hereford Ranch, in Henrietta, Texas. He worked and was mentored by Doug Bennett. His first responsibility was to manage the show barn preparing both the show and sale cattle. Later he became involved in the embryo transplant program as well as marketing.

In 1990, he moved to Nevada to manage John Ascuaga's Jacks Valley Ranch in Carson City. In 1993, he purchased 35 head of cattle from Oregon Hereford Ranch in Hermiston to expand his herd. Since that time he has leased ranches in Nevada and California and currently calls Blue Mountain Ranch, Whitmore, California home. The base of the herd originated in North Dakota and expanded with the purchase from Oregon but the goal has always remained the same: raise sound functional cows with great udders, loads of milk and rib shape that turns grass into pounds. "Culling" is a strong management tool as we do not retain animals that are not efficient and do not reproduce.

Loren and his wife, Terrie, have two grown sons, Hunter and Tanner and daughter-in-law, Erika. Together they strive to develop one of the top cow herds in the country.


They market cattle off the ranch and at select sales in the West. Their cattle are favorites with the commercial cattlemen as well as those seeking purple banners in the show ring.

Mrnak Herefords West offers grass and ranch raised beef for sale for private consumption which provide both taste and health benefits of "home grown."

Whether you are in the seed stock business, commercial cattle production or looking for an enjoyable healthy beef source, Mrnak Herefords West stands behind their product and reputation.

WeWe are pleased to welcome Erika into our family.
