McKay Seed Company was founded by CEO Dan McKay in 1982, when he started McKay Seed Company in conjunction with the family farm. He has led the company ever since, with a single goal: quality. People have to understand that to get a quality crop, you need to plant quality seed. That’s what we provide. The company expanded into their second location in Moses Lake to provide seed to the Columbia Basin in 1992. McKay Seed: Rosalia (formerly Wilhelm Seed) will be the third such operation.
