During the spring of 2013, we set out to identify 20 veterinarians who have had extraordinary influence on the beef or dairy industries. We discovered early on that this would not be a simple task, as people across the industry have tremendous respect and admiration for the veterinarians with whom they work.

To develop our list, we ran a call for nominations multiple times in Bovine Veterinarian, Dairy Herd Management, Drovers/ CattleNetwork and their associated websites and e-newsletters. We asked veterinarians, producers, and industry stakeholders to send us their nominations. The nomination process served as an initial vote, with each individual nomination for a veterinarian counting as a single vote. That process generated a great list of names, many with multiple votes, and we needed a tie-breaker vote to finalize the list of 20. For that, we recruited three individuals with broad experience and knowledge of the veterinary community. That group included: Greg Goodell, DVM, The Dairy Authority, Greeley, Colo.; Bill Swafford, DVM, executive secretary, Academy of Veterinary Consultants (AVC); and Geni Wren, communications director, American Association of Bovine Practitioners (AABP) and former editor of Bovine Veterinarian.

Their votes provided enough separation to identify our final list of 20. We could easily have made the list longer, as virtually all the nominees clearly have had profound influence on their clients, colleagues and industry. However, the final list reads like a “who’s who” in bovine veterinary medicine, with a diverse sample of dairy and beef veterinarians, private practitioners, consultants and academicians. So, here they are.
