Will Brunz, KPA CTP, owns and runs Columbia Mountain Kennels (CMK) along with his wife, Andrea. Now a positive-only trainer, dog-sport competitor, and pet owner, for many years he was an aversive trainer. Will’s wife Andrea launched him on the clicker training path by opting for that sort of training with her new puppy. Initially, Will scoffed, believing that positive training would not work consistently with high-drive working dogs. It was while he was researching for information to support his anti-positive-training position that Will first heard about Karen Pryor Academy (KPA) and the Dog Trainer Professional (DTP) program. “The more I tried to prove her [Andrea] wrong, the more I knew that it was me who was misinformed,” remembers Will.
