Luke Gran

Luke is the owner of Prudenterra, and a Certified Forester with the Society of American Foresters (SAF). What began as the team name of a group project in his thesis capstone course at Iowa State University (B.S. Forestry, 2008), the company was founded shortly thereafter to create a framework to allow Luke and others to help interpret ecological communities and agroecological opportunities to landowners in Iowa. For five years, he worked at the non-profit organization Practical Farmers of Iowa. During that time, Luke continued to work for private landowners part-time while learning from his mentor, naturalist Carl Kurtz, and gaining farming experience. In 2014, he transitioned to full-time work at Prudenterra and began expanding its services to meet the needs of Iowa landowners. Luke is from Newton, Iowa and enjoys the diversity and beauty of Iowa’s native ecosystems. He serves on the board of directors of the Iowa Prairie Network, and lives outside of Nevada, Iowa on a farm with his partner, Sally.
