Dr. Patrick Kelly


After completing a BSc, BSc (Hons) and MSc (Neuroethology) at the University of the Witwatersrand, South Africa, Dr. Pat Kelly received his undergraduate veterinary degree from the University of Pretoria (Onderstepoort), South Africa, in 1982. 

He joined the fledgling Faculty of Veterinary Science at the University of Zimbabwe and taught Physiology until completing a Residency in Small Animal Internal Medicine at North Carolina State University (1985-1987). Thereafter he returned to Zimbabwe and taught Small Animal Medicine at the University of Zimbabwe and completed a PhD (1995). In 2003, he moved to New Zealand and taught in the Veterinary Faculty of Massey University. In 2005, he moved to St. Kitts and Ross University School of Veterinary Medicine where he teaches Small Animal Medicine.
