She then joined the emergency service in Knoxville full time prior to moving to Chattanooga in 2016.

While working at the AESC, Dr. Branam discovered where her interests lie. “I really enjoy working with owners and their pets – I think the relationships that I get to build with both are equally important and enjoyable. I am also really drawn to soft tissue surgery and the problem solving aspect of emergency medicine.”

Dr. Branam has combined her love for medicine, pets, and their people with her business background, taking on the role of hospital administrator for Animal Emergency & Specialty Center. Dr. Branam now oversees operations at both our Knoxville and Chattanooga locations.

“I treat people’s pets as if I was going through the same thing as an owner. If I give it any less effort, I wouldn’t be happy, so I try to maintain that level of attention,” says Dr. Phillips.

Phillips graduated from Pomona College with a bachelor of science in chemistry in 1992. He then attended Tufts University, completing a combined Ph.D. (Medical Genetics) and DVM program at the Sackler School of Biomedical Sciences and the Veterinary School, respectively.

About coming on board…
“I am so blessed to be joining the amazing AESC team in Chattanooga! Everyone from Innovetive and AESC have been welcoming and patient, which makes the transition into a new position that much easier. I am excited to get settled in the new hospital and start working together - I’m sure great things are about to happen!”

My treatment style and philosophy…
“I believe that my job as a veterinary surgeon is to educate owners to the best of my ability so that they can make the best decisions for their pet and family. This often includes an extensive description of disease processes and all treatment options, which may result in the most conservative medical management or an extremely aggressive surgery. I am always happy to work with owners to achieve their individual goals.”

My specialty…
“Surgery is so therapeutic for me! I knew it was my calling because I love anatomy, working with my hands, and immediately correcting a problem in many cases. The diagnostic work-ups, medical management, and client relationships that typically surround my surgical cases are also a lot of fun and something I look forward to.”

Working with the Chattanooga public and their pets…
“Being from Florida, I am excited to begin practicing in the southeast. I hope to build strong relationships with pet owners and the referring veterinary community by being genuine and promoting open communication. I want clients to feel as comfortable with me as they are with their family veterinarians and I want referring veterinarians to feel as comfortable with me as they are with their veterinary school classmates.”


Melissa Miller, DVM Practice Limited to Oncology

A native of central New Jersey, Dr. Miller attended Rutgers University – Cook College for undergraduate studies in animal science and in 2005 went on to pursue a veterinary degree at Ross University School of Veterinary Medicine in St. Kitts. She completed her clinical year of studies at Auburn University and was awarded her doctorate of veterinary medicine in September 2008. Following commencement, Dr. Miller was selected for a small animal rotating surgery and medicine internship at Veterinary Specialists of Rochester in upstate New York where she trained from October 2008 to June 2009.


During the course of her veterinary studies and internship year, Dr. Miller developed a strong interest in medical oncology and elected to pursue advanced training. She completed a specialty oncology internship at MedVet Medical and Cancer Centers for Pets in Columbus, OH in July 2009. Following this internship year, she remained at MedVet as an oncology resident and completed advanced training in June 2013.


From 2013 to January 2016 Dr. Miller worked as a staff medical oncologist at MedVet, growing the weekend Columbus practice as well as establishing satellite oncology services in Dayton, OH and Indianapolis, IN. She was an intricate part of developing and managing the canine lymphoma bone marrow transplant program in Columbus, OH and holds a high clinical interest in ongoing lymphoma studies with transplant medicine and immunotherapy.


After moving to Knoxville, TN in February 2016, Dr. Miller joined the Innovetive PetCare group as a staff medical oncology clinician. She enjoys working with the dynamic teams at the Animal Emergency and Specialty Centers in Knoxville and Chattanooga and is excited to be a part of a leading specialty group in veterinary health care.


“Oncology is a truly unique specialty as it encompasses multiple disciplines and defines the concept of team medicine. When families come to consult about a pet’s cancer, everything is taken into consideration and a plan that fits best for that individual is devised,” says Dr. Miller. “When my own dog, Blue, was diagnosed with lymphoma in December 2015 this became even more evident in my day-to-day care of clients and patients. My goal is to offer everything I can within reason to families that wish to spend additional quality time with their beloved pets.”


Dr. Miller is deeply committed to ongoing cancer research as well as continuing education for clinicians and technicians. Her clinical interests are heavily weighted in the treatment of lymphoid and histiocytic diseases, alternative medicine, and immunotherapy.

Emily Belt, DVM Emergency Clinician

Hailing from southern Illinois, Dr. Belt grew up loving animals of all kinds. Her parents were always supportive and encouraged her to turn her passion into a career. She completed her Bachelors degree in Animal and Dairy Science at Mississippi State University, graduating first in her class. Having fallen in love with the southeast region, she continued to veterinary school at Mississippi State University, graduating in 2016.

During her veterinary studies, Dr. Belt developed interests for companion animal surgery, neurology, and emergency medicine. She was selected for a small animal rotating internship at the University of Illinois and it was during this year that her passion for emergency medicine was founded.

“Emergency medicine allows me to help clients and patients alike in a true time of need. Often, clients come in scared, confused, and sad about something that has happened to their pet. During this emotional period, I get to apply my life’s studies to quickly find a diagnosis, educate the owners about the issue, and find a treatment protocol that not only benefits the pet, but best fits the family’s overall lifestyle. To me, each patient is like my own pet and I give them the same level of commitment.”


After her internship, Dr. Belt felt the pull to return to the southeast region. She recently moved to Chattanooga with her two German Shepherds and four cats. In her free time, she enjoys equestrian eventing, spending time on the lake and river, and hunting.

Dr. Courtney Brunagan

Courtney Brunagan, DVM Emergency Clinician

In high school, Dr. Brunagan started working at a wildlife sanctuary and loved helping and rehabilitating the animals, further dedicating herself to helping animals.


Dr. Brunagan completed her undergraduate schooling and graduated veterinary school from Mississippi State University.

Hanie and Loki

Hanie Elfenbein, DVM Emergency Clinician

Dr. Hanie Elfenbein grew up in Miami, Florida before attending Emory University in Atlanta, GA for her undergraduate training. There she had the opportunity to work with the Capuchin monkeys now famous for throwing cucumbers out of a sense of fairness.


After completing her Bachelor’s degree in Neuroscience and Behavioral Biology, Hanie went on to the University of California, San Diego where she earned a Master’s degree in Neuroscience. She had always considered a career in veterinary medicine but it wasn’t until then that she applied to veterinary school. She believed she would bring something different to clinical medicine, having been involved in the care of animals for nearly 10 years already.


Dr. Elfenbein received her DVM from the University of California, Davis where she also earned a PhD in Animal Behavior as part of the Veterinary Scientist Training Program. Her doctoral thesis examined the interaction between behavioral and physiological health in rhesus macaques at the California National Primate Research Center. Though this seems far off from the veterinary needs of dogs and cats, all animals can develop signs of disease when stressed.  For example, dogs often develop diarrhea when away from their family while cats may become unable to urinate when their environment changes.


In 2016 Dr. Elfenbein moved back to the South to start her career, first landing in Atlanta before making the move to Chattanooga where she now calls home. She splits her time between emergency medicine at the Animal Emergency and Specialty Center and shelter medicine at the Humane Educational Society.


Her extensive cross-disciplinary training has taught Dr. Elfenbein to treat the whole animal and never just the symptoms. Her perspective in veterinary medicine is to always address the underlying cause so that the pet can go back to living a happy, healthy, care-free life with its family.


When not caring for animals Hanie enjoys being outdoors - backpacking, paddle boarding, gardening, and playing fetch with her spoiled dog, Loki.
