Tim O'Byrne is an accomplished cattleman, writer and livestock industry consultant. He gained his extensive knowledge of cattle and horses while cowboying in Alberta, British Columbia and Nevada, eventually holding middle management positions on large scale commercial operations in western Canada (Douglas Lake Ranch, Gang Ranch, Van Raay Farms).

When he and his wife Christine started Calico Beef Consulting in 1994 Tim applied this practical background to meet the challenges of today's evolving livestock industry. They have focused much of their consulting work on humane livestock handling and transportation issues. Tim also serves as an expert witness in livestock related litigation.


Christine O'Byrne handles much of the technical and creative media portion of the business, as well as serving as a full partner.
