Dr. Patricia Whisnant and her team work to produce the best, most healthy Certified Organic beef on their land in Southern Missouri. Each of their cattle is born, raised, and processed on their land and are never confined or exposed to pesticides or synthetic growth hormones. Dr. Whisnant is a proponent in grassfeeding her cattle from birth to finish, which is very rare among cattle farmers. Today, Raincrow Ranch is the largest 100% grass-fed beef producer in the country (Missouri Harvest).
