“Transforming Lives” is what happens within our walls and within your body, mind, and spirit when we work together as a team. We are dedicated, ready and respectful of the work this involves and the remarkable RESULTS that follow.

At our core, we are Chiropractors philosophically rooted in the healing ability of your body and The Zone Technique. We believe, “The Power that Created the body, Heals the body.” We also believe in abiding by natural laws that govern our bodies to keep us in the state of true health. When we evaluate and check your whole body, we are focusing on the nervous system, most specifically your brain, the brain stem and definitive correlating points along the spinal column that control the nerve pathways that reach out to all the tissues of the full body. Your brain and body, free of any interference and imbalance, is able to clearly communicate with a full connection. In this way, not only can pain be eliminated, but all body systems – aka, The Zones: Glandular, Eliminative, Central Nervous, Digestive, Muscular and Circulatory – are prepared to “work smarter, not harder” in order to sustain a body functioning at its very best. We are constantly striving to better ourselves by learning, utilizing and bringing more advanced and effective techniques to our practice for each and every one of our clients. Dr. Gargiula (“Dr. G”) is currently the only chiropractor in eastern Missouri certified in The Zone Technique.

We want to help you live your healthiest life by finding the root cause of your symptoms in a safe, natural and effective way. We are a team that wants to cheer you on as you transform and thrive in living YOUR highest quality of life.



Dr. Tom Gargiula (“Dr. G”)

Dr. Tom Gargiula (“Dr. G”) came to St. Louis in 1987 to attend Logan College of Chiropractic. While in school he met his wife, Sue, who was born and raised in St. Louis. Needless to say they have stayed in St. Louis, enjoy raising their four children and serving the St. Louis Community through Windmill Wellness Center, since 1994. However, Dr. G’s story in chiropractic began many years earlier. While at the chiropractor for their Wellness Adjustments Dr. G’s parents shared with him about their concerns with Dr. G’s health. When Dr. G was born he had Colic (severe abdominal pain, cramps, and vomiting). They were concerned because the pediatrician simply said that he would maybe outgrow it, but offered no solution.

The chiropractor explained to Mr. & Mrs. Gargiula that the nervous system not only controls the muscles but also controls all of the organs and glands of the body. He said that if Dr. G had interference to his nervous system his stomach would not be working properly. Mom immediately asked two important questions. #1: Is it safe to adjust a baby? She had never seen a child get adjusted. He assured her it was safe. #2 How did Dr. G. get nerve interference since he is a new born baby? He explained that it is usually the birth process, which can be traumatic, that causes a child’s first imbalance (Nerve Interference). The great news it that after two adjustments the Colic was gone. They were thrilled.

From that point on, Mr. & Mrs. Gargiula took both Dr. G and his older brother to the chiropractor for regular Wellness/Maintenance Chiropractic check-ups for the simple reason of keeping them healthy.

Growing up under Wellness Chiropractic Care gave Dr. G. a first hand look at what it is like to have a health advantage compared to most of the other children. Getting even a cold was rare for Dr. G. He even remembers in the 5th grade when 75% of the students were out with the flu. He never had a problem and never had a Flu shot. It seems that being healthy in a pro-active way has allowed Dr. G to not only have a very healthy youth but also an incredibly healthy and blessed adulthood as well.

Choosing Chiropractic as a profession was a simple decision for Dr. G. He always loved watching people coming and going at the chiropractor’s office – seeing them get healthy in a way that honored God’s laws about healing. It is quite simple; God made the body to be self-healing. We live our life through our Nervous System. All we need to do is balance the brain and body and the body achieves incredible harmony and healing.

While always in the search for the most effective and efficient ways of getting the best results for patients, Dr. G. found The Zone Technique in 2020. He has poured himself into this healing knowledge and studied thousands of hours and several live seminars to reach true healing mastery. The results he is seeing with his patients is nothing short of remarkable. Very deep and thorough healing that is allowing people to get their lives back.
