ARNOLD STEINER
OWNER & OPERATOR
Arnold was born on a small dairy in central Wisconsin. As a young boy, he found his daily work with cows unenjoyable. Fast forward to 2015, he moved to Northern California, seeing a different side to dairying and crop raising which sparked an interest in his work life.
In 2016, he started driving a silage truck, hauling feed to the local dairymen. He then moved on to dairy service work full-time in 2017, seeing a lot of potential improvements for customers. He began working with them on projects to improve their dairies.
In 2023, Arnold transitioned into managing the dairy service business and operating this dairy business staple, the Northcoast Pumphouse. At the end of the year, the Pumphouse came up for sale and he bought it January 1st, 2024.
Most of his previous customers have stayed with him as he transitioned into owning and operating the Northcoast Pumphouse, but as time goes on, the work is branching out into domestic municipal water pumps. Arnold also works with water treatment facilities to ensure water system safety and functional operation for you!
