Margo Souza joined her family’s dairy farm business in 1984 when the herd of milking cows numbered 600 head. The count grew to over 1,000 milk producing cows with an equal number of replacements growing up toward their production years.

The operation was started by Harry Souza in 1933 when he began accumulating small parcels of adjacent land in California’s San Joaquin Valley. The farm now fills 340 acres and grows alfalfa, corn, and oats for feed. The feed grains are stored in large ground pits and are sold to the local feed mill. The recently computerized feed program keeps highly detailed and accurate records of the farm's Total Mixed Rations.

In 1987, the Souza dairy operations began using computer technology to monitor and optimize the entire dairy operation, which increased the overall efficiency of the business. This trend was as important to the business’s financial management as it was to the farm’s operations. As milk supply and demand fluctuate, prices move up and down accordingly. By monitoring feed and other costs closely, Margo was able to track and manage the business’s performance with up to date information.

In 2013, Margo retired from the dairy industry after several decades.  She is now devoting her time to promoting the cause of agriculture education from the elementary school level through college.
