Hannah Mercurio, DVM, Medical Director

DVM, University of Georgia


Dr. Mercurio received her B.S. from the University of Delaware and graduated with her veterinary degree in 2008 from the University of Georgia College of Veterinary Medicine. During veterinary school she developed strong interests in animal behavior and welfare. She conducted an independent study comparing two lifting methods in weaning pigs. This manuscript was published in the December 2008 edition of the Journal of Veterinary Behavior: Clinical Applications and Research. She was a Geraldine R. Dodge Fellow, receiving support for her work evaluating visceral tumors with ultrasound in sea turtles. She also received funding for a community outreach program in Puerto Rico focusing on educating children about animal care, and providing low-cost veterinary health care clinics in collaboration with local veterinarians.

Dr. Mercurio was very active in student organizations during veterinary school, including the Student Association for Global Awareness, the Student Initiative for Animal Welfare and was one of the founding members of the College's first diversity committee. She was also a supervisor for an emergency relief kennel at the University of Georgia for dogs displaced by Hurricane Katrina.

After graduating from veterinary school, Dr. Mercurio completed a small animal rotating internship at the Friendship Hospital for Animals in Washington, DC. While there, she gained experience in emergency medicine, specialty care and was involved with a large primary care caseload. During her internship, she also developed a special interest in dental care and further explored her interest in behavioral medicine.

Following her internship, Dr. Mercurio served for 2 years as a clinical instructor at The Ohio State University College of Veterinary Medicine in Columbus, OH. There she practiced compassionate and cutting edge wellness and primary care while giving clinical instruction to senior veterinary students.
