The Chiro Co. is a Chiropractor in O'Fallon, MO and was founded by Dr. Rachel O'Brien to serve as a source of all things Chiropractic. Chiropractic care is continuously evolving and becoming a regular aspect in many people's daily lives. It is our mission to cut out the "bandaid treatment" of treating only the symptoms and never the problem. Dr. O'Brien's goal is to provide evidence-based care by finding the underlying cause of pain and stabilizing it for long term relief. The Chiro Co. strives to serve patients with unique treatment plans tailored to each patient's specific needs. We are taking a gimmick-free, evidence-based approach to not only get you well, but to help you stay well.

Movement is key!

Meet Dr. Rachel O'Brien

My name is Dr. Rachel O'Brien, D.C. I am a St. Peter's MO native and attended Lindenwood University where I got my Bachelors degree in Exercise Science with a Minor in Nutrition. I graduated from Lindenwood in 2019 after spending only three short years there. In the fall of 2019, I began the Doctor of Chiropractic program at Logan University in Chesterfield, MO. During my time at Logan, my husband Jarrett and I had our son Baylor when I was only halfway through the three and a half year program. I enjoy spending my time with my family, baking, and reading. In December 2022, I graduated from Logan University and have been eager ever since to serve my community!

I am passionate for spinal complaints such as low back pain, thoracic pain, neck pain, and headaches. I have experience with athletes, pediatrics, prenatal, and general population patients. I firmly believe in remaining active during the healing process of acute injuries, wellness care to prevent future episodes, and receiving regular treatment to improve overall performance and quality of life.
