Zoran Djordjevich, DVM

Chief of Surgery Zoran Djordjevich, or “Dr. George” to most clients and staff, is a native of Yugoslavia. Growing up on a farm, his aspirations of being a veterinarian came at a very young age. He acquired his veterinary medical degree from the University of Belgrade in 1990 and then trained at the Royal Veterinary College in London, England. His persistent quest for innovation has always lead to improvement in his approach and technique paving the way for his great accomplishments in veterinary surgery.

Dr. Djordjevich has the distinct honor of being the first veterinarian in the U.S. to implant the Helica Total Hip Replacement (THR) Systems’ smallest acetabular 24 mm screw cup implant in June 2010. Today, this improvement has been NATIONALLY accepted as the standard for the Helica procedure. Dr. Djordjevich has achieved extremely favorable results for both his patients and clients.

The enhancement of the THR surgery by infusing the implant area with Adult Stem Cells to improve recovery, reduce implant rejection and to stimulate bone formation around the implant is another example of his quest for innovation to achieve the best results for his patients. As Mohnacky Animal Hospital’s Chief of Surgery, Dr. Djordjevich lends his surgical and medical knowledge to any case or doctor throughout the organization.

Joining Mohnacky Animal Hospital (MAH) of Carlsbad in 1998, he has always been an animal advocate by supporting rescue groups and animal help agencies by assisting them in achieving their goals. Dr. Djordjevich is an avid soccer player and also enjoys playing tennis outdoors and table tennis in his spare time. He and his wife Gordana take pleasure in traveling, entertaining family & friends, raising their three sons (Nikolas, Sasha and Filip), and watching after Bubbie their Maltase bundle of joy providing endless comic relief to his family.

Dr. Djordjevich is a member of the AVMA, CVMA and SDCVMA. He has a special interest in orthopedic surgery and advances in natural approaches to veterinary medicine. Dr. Djordjevich came to the United States in 1994 and with his love of this country, he became a citizen in 1999 continuing to work under the philosophy that “with many blessings come many responsibilities to give back”.

Thank you Dr Djordjevich for all you do.
