Marie Lance, DVM

Growing up, Dr. Lance knew she would one day be a veterinarian. She began pursuing her goal when attending Cornell University in Ithaca, New York. Graduating with a BS degree in Animal Science in 1990, she then attended the University of Georgia College for Veterinary Medicine. Receiving her doctorate in 1994, she has since successfully practiced veterinary medicine in hospitals located in Gwinnett and Hall Counties. She has studied Chinese medicine exclusively at the Chi Institute. Her field of practice has encompassed both large and small animals including horses, cattle, sheep, goats, alpacas, llamas, pocket pets and of course dogs and cats.

Her special interests lie in the fields of internal and complementary medicine, reproduction, acupuncture and traditional Chinese medicine and herbal therapy. Dr. Lance is active in the American Veterinary Medical Association, the American Holistic Veterinary Association, and the Georgia Veterinary Medical Association and supports the local service canine units for search and rescue and law enforcement.

Lance Animal Hospital is the culmination of Dr. Lance’s vision to develop an integrative veterinary center that addresses the unique needs of each individual animal. It is her goal to administer the best care possible by integrating traditional medicine and complementary medicine in order to achieve a healthy, well-balanced pet.
