Brian Rutherford, DVM
Chief Medical Officer, Head of Critical Care & Internal Medicine Service

Raised in Knoxville, Brian graduated from the University of Tennessee with his bachelor’s in biology. His first taste for working with animals was as a kennel technician for Fountain City Animal Hospital.

“A friend of mine introduced me to Dr. Mitch and I started picking up weekend work at Mitch’s emergency clinic in 1997. After I got a taste for emergency work, everything else paled in comparison.”

Brian also worked as a marine mammals keeper at the Knoxville Zoo and eventually decided to consider vet school.

Brian obtained his doctorate of veterinary medicine from the University of Tennessee before working at a specialty and emergency practice in Indianapolis. He then completed an emergency and critical care residency in California before returning to Knoxville to begin working at the Animal Emergency and Specialty Center in 2009.

Brian and his team actively manage each patient’s situation on a case-by-case basis. “With each patient I think ahead and make decisions about treatment, not only based on the here and now, but what I can expect will happen within the next six to 12, to 24 hours,” he says.

Despite all the advanced technical equipment used on-site, Brian believes some of the best service he and his team provides day-in and day-out is basic, fundamental nursing care.
“Not only do we treat what physically ails your pet, we also care and provide for your pet’s mental wellbeing. We encourage owners to come by and spend time with their pets during recovery.”

Brian lives in Knoxville with his wife Jennifer and their multiple pets. In his spare time, he enjoys reading, working in the yard and is an avid sports fan. He and Jennifer are expecting their first child in the summer of 2015.

Avian and Exotic Animal Medicine

Katherine Baine, DVM, DABVP
Board Certified in Avian Practice

“During veterinary school one of our professors encouraged us to decipher what in veterinary medicine sparked passion, and for me the answer was easy, working with exotic animal patients. The field presents a unique challenge daily since the anatomy, physiology, and behavior for each animal is very different.”

Katherine graduated from North Carolina State University College of Veterinary Medicine in 2010. After graduation she completed a small animal rotating internship at Blue Pearl Veterinary Partners in Tampa, FL and subsequently completed a 3-year avian and exotic companion mammal residency at the University of Tennessee College of Veterinary medicine.

Katherine’s interest in exotic pets was sparked early on by a feisty little companion, Buster Boyd the budgerigar (parakeet). He was her constant companion over many years and picked up phrases including, “pretty bird” and the catcall. Katherine’s passion for exotic pets was later encouraged by multiple mentors before and during veterinary school.

Jennifer Waller, DVM
Emergency Veterinarian

Jennifer was born and raised in Knoxville, TN. Although she ventured to North Carolina and even St. Kitts and Nevis for her veterinary education, coming home to Knoxville was always part of her long-term plan. After working for a year at a private practice in Kingsport, TN, Jennifer came to work for AESC in the winter of 2010 as an emergency veterinarian.

After just a few months on the job, Jennifer performed a late-night emergency surgery on a dog, keeping him alive in the process. “I went out to talk to the owner and they thanked me for saving their pet’s life. That is when I realized that I had made a difference in the owner’s life, and that this is definitely what I want to be doing,” she says.

In addition to practicing emergency medicine, Jennifer enjoys working with the other compassionate and caring veterinarians at the Animal Emergency and Specialty Center. “In working here, we want to do what’s best for these animals. To me, going above and beyond to take care of them is what stands out about this animal hospital. I’ve learned so much from the other veterinarians. I’ve learned more in one year than most learn in five years.”
