  • While 33 years old and with 3 young children at home, I suddenly became extremely ill and was bed ridden.  I was treated by over a dozen specialists and no one could figure out what was wrong.  I was even referred to the Mayo Clinic, where after a week of testing I was advised to accept that I would always be chronically ill and told that if I wanted to try to leave the house I would be in a wheelchair. I remained in this state of unrelenting sickness for over two years.  Thank goodness for Dr. Jill! After finding her blogs online, I was able to see her in person where she looked me in the eye and said reassuringly “I will figure this out.  That is what I do. I won’t give up until we find something that will help you start feeling better.”  And she did and more! She found the cause of my illness, treated me for it, and now I am back to full health! I will forever be grateful for Dr. Jill and the life that I have back now thanks to her!  I highly recommend Dr. Jill.  She is the most intelligent doctor I have ever met and is truly gifted in diagnosing and treating patients with complex medical issues.

  • Although I know my daughter has shared her news, I must send my own praise for all that you have done. I wish I had a picture of the GI Physician’s face when he came out to talk to me after the colonoscopy. Quote: “There is nothing there!” He was amazed that she had no signs of Crohn’s… the biopsies came back negative!!” We are so grateful to you and your staff for being there for her. Your patients and the love that came across for her healing was always felt and I’m especially grateful to you for accepting her into your practice.

  • Dr. Jill has changed simply changed my life. I feel better than I have felt in years. I have more energy, more joy, and I can’t believe how fast I improved. In one day, I started noticing results and 3 months later, the improvement continues. For a decade, I had to give up more and more activities that I loved, due to inflammation and pain. I am now pain free, headache free and loving my new body and enjoying the activities that bring me joy. I can’t say that the changes I made were easy, but they are worth it. I am looking forward to the possibilities of my future. Thank you Dr. Jill for your intuitive wisdom, experience, and for giving me my life back!

  • Jill C’s lectures in the Good Gut were some of the best I have heard in A4m. Full of clinical pearls, she knows her stuff. I highly recommend we see more of her at A4M/MMI.

  • I wanted to say THANK YOU!!!! When I woke up this morning I hit the lowest I have weighed since I was in High School and my waist size is actually smaller. Not to mention, I feel like a totally different person. My goals and outlook on life have totally changed because of you and your expert analysis, guidance and most of all SUPPORT.

    I will never forget sitting in your office and hearing you say “When we take care of the this bacteria over growth you will start loosing weight” and thinking it couldn’t be that easy… but it was. With proper diet, the right supplements and medicine it’s made a greater change in my life then you will every know. I tell everyone I see about… how spectacular you have been. As I stated above you have changed my life and all in less than 6 months!!!!

  • I believe that people who go to functional medicine docs are typically desperate. We are the patients who are at the end of our proverbial rope, tired of taking drug after drug with no relief, and who traditional MDs don’t know what to do with. We just dream of a life without pain and to be able to function again. Thanks to Dr. Carnahan, I have no signs of the rheumatoid arthritis I was diagnosed with in 2012, and I’m regaining function that was stolen by the MS I was diagnosed with in 1991. I am recovering and regaining my life. Dr. Jill Carnahan is simply phenomenal.

  • I wanted you to know that as an Integrative Functional Medicine doctor you are 10 out of 10. In fact I tell people that you are the only one in the USA that could effectively treat my condition, and I really believe that 🙂
