Ken Welle
DVM, Diplomate ABVP (Avian)
Dr. Welle is a board-certified avian veterinarian. He has long been captivated by the feathered dinosaurs that are birds and enjoys the unique challenges of keeping them and other unusual creatures healthy and well-adjusted. Four macaws and six chickens haunt his farm along with one dog and four goats.
After graduating from the University of Illinois with his DVM, Dr. Ken Welle was in general practice for seven years before gaining board certification in Avian Practice from the American Board of Veterinary Practitioners. For the next 15 years his private practice was limited to birds and other non-traditional pets and he worked with a local zoo. His passion for this field led him to return as faculty to the University of Illinois in 2011 so he could share his knowledge and experience with veterinary students. In addition, Dr. Welle has been very active in the Association of Avian Veterinarians serving as a board member, treasurer, and president, and has been on the residency committee of the American Board of Veterinary Practitioners for over a decade. He has also lectured at local, national, and international conferences.
