Conditions We Have Helped
What Is Functional Medicine?
Our world has gotten increasingly unhealthy, and people are experiencing symptoms at younger ages—digestive issues, fatigue, brain fog, thyroid problems, insomnia, weight changes, memory struggles, cardiovascular concerns, and more. But here’s the truth: you don’t have to live with these problems. That’s where Functional Medicine comes in. Unlike conventional medicine, which often just masks symptoms with medications, Functional Medicine looks deeper. We focus on the root cause of chronic health issues by considering lifestyle, environment, genetics, and more. In our clinic, we take the time to listen, run advanced Functional Medicine lab tests when needed, and use proven programs developed from years of research and real-world results. We also offer Brain-Based Therapy to address underlying neurological imbalances. Together, these tools provide a natural, personalized path to eliminating symptoms, restoring health, regaining energy, and helping you thrive long-term.

5 Starr Experience , went from headaches everyday for forty years to very few in three months. And new hope, now that I know pain free is possible. I can't begin to tell you what I've been through, never thought headache free was possible for me. I'm living a new life. Thanks Doc.

So I was diagnosed with M.S. in 2009. I was going down hill fast lately. Dr. Duquette and Kendra are the best giving you all the information you will need to get healthy and stay healthy. I am on the right track due to the Duquette's I give them so much love. The 2 hour drive is well worth it!

Dr. Duquette and his amazing staff get to the root of the issues and develop a lifestyle plan that alters the course of these dreaded diseases versus just masking symptoms. I still have a ways to go in the program, but it has absolutely changed my life! I couldn't be more thankful and appreciative that our paths crossed.
Casey Curry
He and his staff have given me the tools to move ahead on my own, to listen to my body, and to look at health in an entirely new way. I am forever grateful and would recommend him to anyone.

I would recommend anyone with any health problem who lives in central Illinois see Dr. Duquette before they waste their time with any other doctor.

I feel like I have been given my life back :). My IBS symptoms are non-existent as long as I support my body with good, clean foods. I follow the tips provided in the program to focus on positive mental health, manage my stress, and have a better outlook on life. This has greatly reduced my anxiety, and I don't notice depression at all.

Dr Duquette has helped me learn what my body needs to be healthy. I was able to learn new patterns and behaviors through his guidance. He's very kind and easily accessible...always willing to talk/call you back to discuss concerns.
