Biography Paul D. Virkler

Dr. Paul Virkler was born and raised on a small dairy farm in Lewis County, NY.

He attended Cornell University where he obtained both his BS and DVM and then spent seven years as a cattle veterinarian at Attica Veterinary Associates in Western NY.

He subsequently worked at DeLaval as a technical services veterinarian covering North America and then at the Animal Health Diagnostic Center in the Veterinary Support Services unit. Currently Dr. Virkler is working as an extension veterinarian for Quality Milk Production Services where he provides science based advice to dairy producers and their veterinarians as an integral part of their udder health and milk quality teams.
