Dr. Johnston was born and raised in Corpus Christi, Texas, and attended Baylor University. After graduating, he worked as a high school science teacher and basketball coach. While teaching, Dr. Johnston felt the call to pursue veterinary medicine and attended Texas A&M University in College Station. After graduation, he practiced medicine at a five doctor hospital in North Dallas and, in 2016, he became the proud owner of Towne Center Animal Hospital and Pet Hotel. Dr. Johnston likes blending his teaching background with his veterinary training to educate pet owners about the health of their animals. While he enjoys all aspects of veterinary medicine, his special interests include dentistry and surgery.
To relax, he enjoys fishing, playing sports, and is an avid reader. He is happily married to his wife, Lauren, and they have two boys, Cooper and Carter, and a little girl, Caroline. His family also includes two doodles, Helen and Eleanor. Dr. Johnston's extended family has no shortage of animal caretakers because his identical twin brother is a veterinarian in Waco and his brother-in-law is a veterinarian in Lufkin.
