Brad Rosonke, DVM and Cathy Rosonke ~ Owners
Dr. Rosonke graduated with honors from Kansas State University School of Veterinary Medicine in 1994. After graduating, Dr. Rosonke worked at Sea World followed by the Oregon Coast Aquarium where he helped to rehabilitate Keiko, the killer whale from the movie Free Willy. Since 1998, Dr. Rosonke has worked exclusively with companion and exotic pets here in the North Scottsdale area. He is a member of the American Animal Hospital Association, the American Veterinary Medical Association, and the Arizona Veterinary Medical Association.

In addition to managing the day-to-day operations of the hospital, Cathy designs all of the hospital's marketing programs.

Dr. and Cathy Rosonke are both South Dakota natives whose paths crossed here in Phoenix in 1999. They were married in 2001 and set out to combine their passion for animals and talent for business to create a family owned company that would become Hillside Animal Hospital. The Rosonke family includes Lexi (West Highland Terrier) and Angus (Terrier Mix). They fully understand the power of the human~animal bond, and can relate to pet owners who see their pets as their "children". It's the understanding of the precious role that pets play in their owner's lives that is the foundation of Hillside Animal Hospital.
