The doctors with a dog

Our Team of Veterinarians

Our team of veterinarians are on a mission to serve their clients as well as they serve their patients! These DVMs are not only incredibly talented veterinarians, they also have a true servant’s heart in their approach to both client and patient care. They are excited to spend ample time at each appointment (we offer hour-long appointments!) getting to know you and your dog, and their goal is to answer every question that you have before the appointment is over. Our DVM team promises to partner with you to provide exceptional medical care to your dog. 

We believe at Good Dog Veterinary Care that two sets of heads are always better than one, and our team of veterinarians work together to collaborate on cases each day. Our DVM team routinely scrubs into surgeries together, reviews diagnostic cases together, and approaches every patient from a “team mentality.” We believe that open communication and collaboration among our DVM team only elevates our standard of incredibly high patient care! Our team of veterinarians is led by our Lead Veterinarian who oversees the medical safety of every patient in our care. We are so proud of our team of veterinarians, and we cannot wait for you and your “Good Dog” to meet our team!

Danielle Tillis, DVM


Dr. Danielle Tillis serves as the Lead Veterinarian at Good Dog Veterinary Care Smyrna. Dr. Tillis and Dr. Singletary partner together each day to ensure every patient in our care at both Good Dog Veterinary Care West Cobb and Good Dog Veterinary Care Smyrna receives the highest standard of medical care. Dr. Tillis’ responsibilities as Lead Veterinarian include leading the medical and client care team at Smyrna as well as collaborating with other members of the DVM Smyrna Team to ensure exceptional patient care.
While Dr. Tillis’ entire family works in the human medical field, she realized early on that human medicine wasn’t her calling. However, she couldn’t shake her passion for medicine and hands-on care. After a summer job as a veterinary assistant, she knew veterinary medicine was her passion. Why not put her lifelong love of animals to good use, thought Dr. Tillis, by serving as a veterinarian? She hasn’t looked back since!
Dr. Tillis is a “double dawg” and graduated from the University of Georgia College of Veterinary Medicine. In fact, Dr. Tillis and Dr. Singletary were classmates and graduated in the same class from the UGA CVM! Danielle lives with her husband James, two children, and Odin (their “goofball” of a Great Dane). Dr. Tillis and her family love all things Georgia sports: the Braves, the Falcons, Atlanta United, and UGA football. Chop on. Rise up. Unite and conquer. And of course, Go Dawgs!

Greer Pratt, DVM

West Cobb + Smyrna

Dr. Greer Gafford Pratt has always had a deep love for animals, and she grew up surrounding herself with animals of all kinds. When she was nine years old, Dr. Pratt spent the morning shadowing her family’s veterinarian, where she instantly fell in love with the profession. When her mother came to pick her up at lunch, she begged her to stay the rest of the day. From that day forward, Dr. Pratt knew her dream was to become a veterinarian!

Dr. Pratt grew up in Smyrna, Georgia. She completed her undergraduate degree at The University of Georgia (Go Dawgs!), where she competed on UGA’s Cross Country and Track and Field teams. Following her graduation from UGA, she made a big move from Athens, Georgia to Grenada, West Indies to begin her veterinary education at St. George’s University School of Veterinary Medicine. On the island, Dr. Pratt gained experience with animals ranging from tiny puppies to the Leatherback Sea Turtle, the largest sea turtle in the world! For her final year of veterinary school, Dr. Pratt returned to Athens, Georgia to complete her clinical rotations at The University of Georgia College of Veterinary Medicine.

Dr. Pratt’s special interests include dentistry, dermatology, and soft tissue surgery. She looks forward to helping your “Good Dog” live their very best life!

In their free time Dr. Pratt, her husband, and their yellow labrador River will be found exploring the outdoors (River’s preference is to be near any body of water)!
