Meet Dr. Zach Thompson, DC - Within Chiropractic in Colleyville, TX

Dr. Zach Thompson founded Within Chiropractic to give Colleyville-area patients something they rarely find: a thorough exam, honest answers, and a care plan built around their actual life.

Why Dr. Thompson Became a Chiropractor

At 18, Dr. Thompson was a college football player who pushed too hard on squats and spent the next six months in severe pain just walking to class. He was taking eight Advil and two sleeping pills every night just to function. The advice he received: stretch your hamstrings and it’ll feel better eventually.

It didn’t. That summer he sat down on the couch before dinner and couldn’t get up. He was stuck there the entire night.

An emergency visit to an orthopedic surgeon, MRIs, X-rays. Nothing pointed to surgery. The doctor gave him two options: a bottle of Vicodin, or the chiropractor down the hall. He chose the chiropractor. Within two weeks he was back in the gym and the back pain was gone.

That was the moment he decided what he wanted to do with his life. He didn’t want another 18-year-old spending six months suffering through back pain that, in his case, was straightforward to fix once someone actually addressed it correctly.

“Six months of pain ended in two weeks.”

Education and Training

Dr. Thompson went on to earn his Bachelor of Science in Exercise Science from Salisbury University before completing his Doctor of Chiropractic degree at Parker University in Dallas. That exercise science foundation shapes how he thinks about every patient. He’s not just looking at where it hurts. He’s assessing how the body moves, how load is distributed, and what the structure underneath is doing.

What Dr. Thompson Specializes In

Dr. Thompson’s clinical focus is on active adults in the Colleyville area who are dealing with pain that has gone unexplained or undertreated. His approach starts with a thorough exam and ends with a specific plan, because his own experience taught him exactly what it costs when that step gets skipped.

For patients dealing with herniated or bulging discs, chronic sciatica, or nerve-related back pain, spinal decompression is one of the most effective tools available without surgery. Dr. Thompson incorporates it as part of a broader care plan when the exam and imaging indicate disc involvement.

Digital posture analysis is part of every new patient exam at Within Chiropractic. Dr. Thompson uses objective posture measurements alongside X-ray findings to identify the structural patterns driving chronic pain, then builds a correction plan around fixing them over time.

Dr. Thompson works with personal injury patients throughout the Colleyville area following car accidents and other trauma. Thorough clinical documentation is part of the process from day one, which matters both for recovery outcomes and for insurance claims.

His exercise science background is particularly relevant here. Dr. Thompson assesses sports injuries with an understanding of movement mechanics that goes beyond chiropractic alone, which helps identify not just what got injured but what created the conditions for the injury in the first place.
