The Blach family settled in the Yuma area in 1887 where they were involved in farming and ranching. Randy is the eighth of nine children born to Perry and Teresa Blach, and he remains actively involved in all aspects of the family operation. After graduating from Colorado State University, Blach was hired by CattleFax in the fall of 1980 and went to work full time in January 1981 as an analyst trainee before becoming a Regional Market Analyst. In 1985 he was promoted to Director of Market Analysis, a position he held for 15 years until the retirement of his friend and mentor Topper Thorpe. In 2001, Blach was named executive vice president.
