Dr. Brittany Ellersick

Dr. Ellersick's Bio

Dr. Brittany Ellersick works out of 45th location. She was born and raised outside of Chicago, Illinois. A collegiate bowling scholarship gave her the opportunity to embark on a new journey to Texas. She obtained her Bachelor of Science in animal science at West Texas A&M University in 2015 and her Doctor of Veterinary Medicine from Midwestern University College of Veterinary Medicine in May 2019. For some, Dr. Ellersick may look familiar, as she formerly worked at Swann Animal Clinic as a technician. She is very excited to be joining the team once again as a veterinarian.

Dr. Ellersick’s professional interests include dentistry, ophthalmology, and neurology. She also enjoys traveling, hiking, cooking, and watching Netflix, which she enjoys with a cup of coffee and her two pets, Gunner, an Australian shepherd/heeler mix, and Paisley, a tortie calico kitty. Dr. Ellersick is blessed to be in the Lone Star State and looks forward to serving the community she now excitedly calls home.
