Emergency Veterinarians

  • Stefanie Sullivan,

    Dr. Sullivan is a Chattanooga native. She graduated from Ooltewah High School and obtained a Bachelors of Science degree in Biology from the University of Tennessee at Chattanooga. She subsequently made her way to an island (Grand Cayman to be exact), where she laid on the beach, snorkeled, dove, and studied Veterinary Medicine. After three years of living on island time and completing her course work, she made her way to Indiana where she finished her clinical year at Purdue University. She received her Veterinary degree in 2009 from St. Matthew’s University.
    Dr. Sullivan moved back to Chattanooga and began working at an emergency and specialty
    practice. She did a one year rotating internship and then worked for a year as an emergency
    clinician. She has spent the last few years working and training for a residency in emergency and critical care.
    In her free time, she enjoys getting outside, traveling and spending time with friends and family. She and her boyfriend have five dogs and one kitten that keep them busy (Timber, Piper, Ziggy, Remi, Ashe, and Cheez-it).

  • Kim Lucy,

    Dr. Lucy is an alumna of Rollins College in Winter Park, Florida, and the College of Veterinary Medicine at the University of Tennessee-Knoxville. She completed a one year internship at BluePearl in Lousville, Kentucky, and has since worked exclusively in emergency care. Dr. Lucy enjoys the variety of cases that are seen and treated in an ER setting. Outside of work, Dr. Lucy stays very active in outdoor activities including white water kayaking, running, and hiking with her dogs. She has two dogs: Bert (a year old border collie mix) and Shanti (a four year old pointer mix). Shanti was a patient of Dr. Lucy's during her internship. Shanti basically lived at the clinic while receiving treatment for her severe leg wound, and she eventually worked her way from the hospital into Dr. Lucy's home permanently. Additionally, Dr. Lucy has two cats named after sea creatures : Diadema (sea urchin) and Goby (fish).

  • Christopher Perry,

    Dr. Christopher Perry is an emergency veterinarian at VCSG. Dr. Perry had aspirations of becoming a veterinarian since his early childhood years in Georgia. Prior to attending the University of Georgia for his veterinary degree, Dr. Perry held a wide range of animal related jobs from working in kennels, to milking dairy cows, and even breeding thoroughbred horses. Despite this wide range of experience with animals of all shapes and sizes, Dr. Perry still holds dogs and cats as his favorite. This love of companion animals propelled him to complete advanced training during a one year emergency internship. The training enhanced his medical skills and commitment to delivering the best in patient care. Following his internship, Dr. Perry spent almost two years in general practice in Virginia before returning home to Chattanooga.

    When not practicing medicine, Dr. Perry is most likely to be found enjoying the local outdoor activities with his Border Collie, Zoe. Additionally, he is an avid traveler. In fact, his enthusiasm for travel led him to study veterinary medicine in Brazil while obtaining his DVM degree. Dr. Perry says that he is excited to serve clients and their pets by maintaining the quality of care that VCSG is known for providing.

  • Jake Barnett, DVM

    Dr. Jake Barnett is another local that grew up on a farm in Chattanooga and has been away for the past 10 years pursuing his Veterinary career.

He attended the University of Tennessee college of Veterinary Medicine and received his degree in 2015. After school Dr. Barnett practiced general medicine on the other side of the country near Sacramento, California.

    In his free time, Dr. Barnett enjoys all aspects of the outdoors. He can often be seen kayaking, hunting, fly fishing, mountain biking, or hiking. He is scuba certified and truly has a passion for all animals on the land
