Isdale Chiropractic Clinic has been family-owned from the beginning: founded by Dr. Sid Isdale, carried forward by his sons Dr. Scott and Dr. Shawn, and now joined by Dr. Dallas Johnston, treating patients across Killeen, Harker Heights, Nolanville, Copperas Cove, Salado, Belton and Fort Hood.

Dr. Scott decided he wanted to be a chiropractor at twelve years old, listening to his father, Dr. Sid Isdale, talk about the results his patients experienced through chiropractic care.
He joined the clinic in August of 1975, carrying his father's passion for the work into a second generation of the practice. Outside the clinic, he spends his time woodworking, reading and hunting.
Dr. Shawn was born and raised in Killeen, the youngest of five brothers, three of whom also became chiropractors. He graduated from Killeen High School in 1978 before attending Texas Chiropractic College in Pasadena, TX.
He earned his Doctor of Chiropractic degree in 1984 and joined the practice alongside his father, Dr. Sid, and his brother, Dr. Scott, in March of 1985.


Born and raised in Killeen to two parents who served in the military, Dr. Dallas Johnston served in the Marine Corps before discovering chiropractic care through his fiancee's father, also a chiropractor.
He went on to Parker University in Dallas, TX, enrolling in the Doctor of Chiropractic program in the fall of 2013, where he discovered the power of the body's nervous system and its innate ability to heal.
