About Us: 
Oak Hill Ag Service  

Cory Olson grew up on a dairy farm and agriculture has been central throughout his life. After earning a crop and weed science degree from North Dakota State University, he returned home to work directly with growers. In 2004, Cory and his brother, Nick, founded Oak Hill Seeds. That has now evolved into Oak Hill Ag Service — a full-service operation offering Pioneer® brand seed, expert agronomy services, and much more.
