Windy Ridge Simmentals LLC was founded in 2004 by Tom and Kristi (Mobley) Rathje. Both attended Iowa State University and the University of Nebraska, with Kristi completing her B.S. in Animal Science and Tom his M.S. and Ph.D. degrees in livestock genetics and an MBA degree. Tom and Kristi have three children: Katie, Grant and Josie,  who have been active in the operation as well as AJSA youth events.

Kristi is the operating manager for Windy Ridge and is our primary contact for sales and customer service. Tom spends his daytime hours as the Chief Technical Officer for DNA Swine Genetics where he is responsible for the genetic improvement program and implementation of new technologies in the nucleus herds. Improving genetics is a part of everything we do and a lifelong passion.

We strive to produce cattle that have the ability to help you achieve your goals. Few things are more important to us than your success. Whether you define success in the show ring, the donor pen or in fulfilling your production goals, we produce the type and kind of cattle that will help you to be successful. We thoughtfully select cows to enter our donor program after proving their ability to produce high quality progeny that will excel within the Simmental breed. Our calves are the result of matings from industry-leading sires with predictable genetics that complement the power of our donor battery.

Customer service, earning your trust and ensuring your satisfaction are very important to us. At Windy Ridge Simmentals, you will be treated with respect and will find a group of people who love to talk cattle and find ways to help you be successful. We recognize and support the youth that are the future of our industry and do our best to assist them in any way possible. We stand behind all the cattle and embryos we sell, so you can buy with confidence. We appreciate your interest in our program and invite you to contact us to learn more about what we have to offer.
