I write a monthly article on preventative medicine, and I have been published in the Annals of Pharmacology as well as the State Medical Journal. I was the “Supervising Physician” for the 2008 documentary Good Meat: "How the Lakota Got Fat and Beau LeBeau Saved Himself."

After years of witnessing the destructive forces of overindulgence, I developed the Dakota Diet, a healthy eating plan that teaches how to lose weight and improve health now and throughout life. I am also a member of Rapid City Medical Center’s Bariatric & Metabolic Institute, a team of highly educated staff working to treat obesity.
