Jeff Troost is a fourth-generation California dairy farmer. The dairy is a family operation. Jeff, alongside his sons Johnny, Jayson, and Travys, now runs the day-to-day dairy operations. Jeff moved the dairy to Chowchilla in 1993 as development pushed them out of Southern California. Today, Troost Dairy employs 23 local people.
Jeff and his wife, Dana, raised four sons in the Chowchilla community, and the family has stayed deeply involved in local schools, sports, 4-H, FFA, and Cornerstone Community Church.
The Troost Dairy approach is simple: take care of your animals, treat people fairly, and be a good steward of your resources. To stay successful in dairy, you have to be willing to innovate and keep an eye on what is ahead.
That mindset is what led Troost Dairy to build a digester. “It created an additional source of revenue, but it was also a way to be part of dairy’s sustainability story,” said Troost.
They chose to work with Maas Energy Works because the values aligned and the company had a strong reputation in the area.
