Bill Brothers graduated from Cornell University, where he studied wildlife conservation and animal science. After teaching for several years, he managed several humane and animal control agencies. In 1985, he founded Animal Care Equipment & Services (ACES) to provide equipment, training, and other services to professionals who work with animals. In 1990, the Humane Society of the United States asked Bill to create a humanely-oriented course of instruction in chemical immobilization. Thousands of students have completed ACES’ chemical capture certification training, and it continues to be highly acclaimed and in demand.
