Dr Callum Bennie

Dr. Callum hails from the trendy inner west of Sydney and has wanted to be a vet for as long as he can remember.

While studying veterinary medicine at the University of Sydney he conducted research into antibiotic therapy for mycobacterial skin diseases in cats – a research project that sparked his love of veterinary dermatology. After a stint in small animal practice in Canberra, he relocated back to Sydney and undertook an intensive small animal medicine internship prior to pursuing specialty training in dermatology at Colorado State University’s James L. Voss Veterinary Teaching Hospital.

Dr. Callum is thrilled to be home and now working with the Veterinary Dermatology Clinic. He loves all aspects of dermatology and looks forward to helping you and your pet!
