Our Team

We’ve got a worthy team on hand.

As we continue to grow as a company, so does our staff’s expertise in developing comprehensive dairy solutions for the ever changing needs of dairy farmers. Since our own time as dairymen, we’ve wanted to give new life to the traditional milking methods in order to increase overall farm efficiency. The relationship our staff builds with every customer runs deep—customers know we always have their best interests in mind.

It’s our extraordinary group of people that make it possible to operate a company that we’re proud to call Modesto Dairy Solutions.
