Born in Fargo, North Dakota and grew up in central Iowa (Story City). My family farms in Minnesota and North Dakota and I became interested in agronomy and helping farmers at an early age. I worked for industry and then started at the University of Idaho in 1999. My husband, Tom Salaiz, is also involved in potatoes as the Western Regional Agronomy manager for McCain Foods. Participated in the Big Brother/Big Sister program and am involved in musical groups as a percussionist.
