Brookside Agra Celebrates 30 Years!

In 1985, Don and Margaret Riesenberg founded Brookside Agra in their Highland, Illinois home. After serving nearly 37 years in the U.S. Navy and having worked for several Fortune 500 companies, Don started Brookside realizing that he could achieve the same or better results using all-natural ingredients instead of chemicals in specialty feed additives and agricultural and environmental products.

For 30 years, Don has served as president and lead researcher for Brookside Agra. Because of Don’s dedication to the development and research of all-natural and organic products for the agricultural and environmental markets, Brookside Agra has attained worldwide recognition for its products.

With five generations of farming and feed manufacturing expertise, Brookside Agra is still a family-run business and boasts an impressive lineup of industry experts who continue to research and develop new products.
