Dr. Thomas, DVM

Dr. Stephanie Thomas grew up in Baton Rouge, Louisiana, and was the salutatorian of the second graduating class from Christian Life Academy. She began her college career at Louisiana State University but took a hiatus before graduating to raise her children. After establishing her children with a good foundation she returned to LSU to become a member of the LSU School of Veterinary Medicine Class of 2013. As a non-traditional student people would hear her classmates often refer to her affectionately as “Mama Steph” around campus. This was especially true in the equine hospital, where she spent much of her time. Dr. Thomas has always had a love of animals but was drawn to veterinary medicine after volunteering with the LSU SVM faculty and students for the equine rescue effort at Lamar Dixon following Hurricane Katrina. Dr. Thomas prefers the clinical side of practice where she is able to work with her clients on a daily basis to ensure an optimum quality of life for their furry family members. Dr. Thomas is a member of the American Veterinary Medical Association, Louisiana Veterinary Medical Association, and Baton Rouge Veterinary Medical Association.

Dr. Thomas currently resides in Denham Springs with her husband, Derrel, in a house that seems to grow quieter by the year with only one of her five children still living at home. Now home has become a farm and is filled with animals including but not limited to eight chickens, four goats, three birds, two cats, one horse, one miniature donkey and one dog,lacking only the proverbial partridge in a pear tree.

In her extremely limited spare time, Dr. Stephanie enjoys motorcycle riding, horseback riding, and scuba diving. She also enjoys traveling and has combined that with her other hobbies at various destinations including England, France, Australia, Isla Roatan, Philippines, Mexico, and New Zealand. Dr. Stephanie’s favorite pastime by far is spending time with her only granddaughter, Casey Ann, who knows Dr. Stephanie as "Emme" and Derrel as "Grumps."

Dr. McWhorter’s hobbies include reading, hiking, and listening to showtunes. Most of her spare time is spent in the company of family and friends, which includes going home to Oklahoma to visit her parents and sister as much as possible. She also travels to Boston annually to visit her best friend.
