Dr. Hadden was born and raised in the small town of Greenville, Ohio. Growing up he was very active and loved to play any sport, particularly soccer and baseball. After graduating from high school, he went to Miami University in Oxford, Ohio where he studied Exercise Science and earned a Bachelor’s degree in Health and Sport Studies.  In 2001, Dr. Hadden moved to Missouri to attend Logan College of Chiropractic.  After a rigorous 3.5 years of school, he earned his Doctor of Chiropractic degree. He spent his first few years of practice working for other Doctors and learning different styles and techniques of Chiropractic. In 2010 he took over a practice in O’fallon, MO.  He owned that practice for 10 years until joining Frontier Integrated Health Center in June, 2020. 

Dr. Hadden loves being able to help people reduce and eliminate conditions like low back pain, neck pain, headaches, and many more.  Dr. Hadden loves hearing stories from his patients about how they can go back to work or play with their kids because he was able to help them. 

Dr. Hadden currently lives in St. Charles County with his wife, Lindsey, and their two sons Joshua and Tommy. Lindsey is a Pharmacist for The Medicine Shoppe in St. Charles. They enjoy spending every spare minute with their children and they look forward to raising them in the O’Fallon and St. Charles County Community.

Dr. Adam Dettenmeier grew up in southern Illinois near St. Louis, Missouri. Dr. Dettenmeier was very involved in the Boy Scouts of America and the Order of the Arrow earning his Eagle Scout at the age of 17. Active in a multitude of sports growing up, his main passion was ice hockey which he continued to play through college.  In 2018, he graduated from Saint Louis University with a Bachelor degree in both Health Sciences and Accounting. Dr. Dettenmeier then attended Logan University’s College of Chiropractic and graduated in 2021 with a degree in Doctor of Chiropractic. He also attained certification in Acupuncture as part of his studies.

Dr. Dettenmeier’s love for chiropractic began while playing hockey and sustaining injuries from this continuous contact sport. While ibuprofen and acetaminophen would take the edge off and help him to continue playing, the pain still lingered. One of his youth hockey coaches was a chiropractor who helped him realize that the chiropractic adjustment reduced the need for medications. He also gained understanding that chiropractic was both a tool to help the body repair itself and a way to maintain a healthy lifestyle. Dr. Dettenmeier wants to help heal patients of all ages and show them how chiropractic care can help the body heal itself.

A little about me. Helping people become healthier, better, faster, stronger, and reach their optimal potential has always been one of my greatest passions. With this passion in mind, I completed my undergraduate studies at Lindenwood University where I majored in Athletic Training and Exercise Science, with a minor in Psychology. After graduating I worked as the Head Athletic Trainer at a local high school where I got to further my passion for helping clients overcome and prevent injuries. I got to work with team coaches and strength and conditioning coaches to develop training programs to help our teams perform at their peak potential while working to prevent injury. 

This was a great job and I loved every second of it. I couldn’t get enough, helping clients get back to what they love was icing on the cake. However, I always felt as though there was something more, I could be doing to help more people. So, I did a lot of research into other professions and even higher education. When I first told family and close friends that I was considering going back to school, most of them thought I had gone mad. But seeing my passion for helping others, they were all incredibly supportive, nonetheless. I honestly could not thank my parents and my wife enough for helping me to work through the planning and logistics of it all.

So, I started my search. I investigated all possible options available to me. 

Then I remember back to my childhood. I was quite an active child, and rather prone to getting myself into trouble that most often culminated in bumps, bruises, and sometimes a trip to the doctor’s office. The doctor of choice was, more often than not, an amazing Chiropractic Physician. This was a huge light-bulb moment! I started looking into Chiropractic: what all they can do, how they treat clients, how they help people, and what their philosophy on healthcare is. The more I researched Chiropractic, the more excited I got about this option! Almost everything was lining up with my outlook on client care. It was amazing! And even better, one of the best chiropractic schools in the country is only a few minutes away!
