Dr. Robert M. Miller, DVM, has contributed to Western Horseman magazine as a writer and cartoonist since 1949. In the January 2011 issue, "The Horsemanship Revolution" tells of the vital role Western Horseman played in spreading the word on natural horsemanship and imprint training, of which Dr. Miller was a leading pioneer.
John McComber has cowboyed and started colts in California, Colorado, Nevada and Wyoming. He lives in Winnemucca, Nevada, where he trains horses for the public. He also shows working cow horses. He bases much of his program on the premise that a proper horsemanship foundation must be based on knowledge and understanding of the horse's anatomy. The December 2010 issue of Western Horseman includes John's article, "5 Cow Horse Fundamentals."
