What Others are saying....
“I paid a lot of the money to have mine read by a functional medicine doctor. They said it was unremarkable. Then I met Dr. Gail, and had her read my results. Wow, she told me a LOT about my health! The results provided a great starting place for my recovery.“ Holly N
My time with Dr. Clayton literally changed my life!! I am very appreciative of the help she provided and the amazing guidance to bring my health back to me! ~ Roxanne C.
Dr. Clayton is an artist when it comes to teasing out my complicated case. Extremely helpful like none other. ~ Jacqueline B.
Everything was exceptional. I appreciate the easy communication and the patient portal resources. ~ Joshua M.
Dr. G Clayton worked diligently towards resolution of my complicated GI issues. Often times what was recommended did not work for me, and she continued until she found the answer. She was transparent in sharing her own experiences with like issues which gave me hope for my outcomes. In explaining how the body works and the related labs, she was clear in her explanation and allowed questions. One of the best things I like about Dr. G was that everything she said in the sessions was sent to me through the portal, which meant I did not have to rely on my memory for the instructions. I referred her to someone immediately the day of our last session because she was very helpful to me. Thank you, Dr. Gail Clayton.~ Rita S.
Dr. Gail, I have already recommended your services to one friend and will continue to do so!

Thank you and blessings to you for your commitment to your clients! ~ Debbie P.
