"I've been working with Sherrlyn for almost a year, and it's evident how professional, caring, intelligent, and an expert she is with natural medicine. As her patient, I've experienced progressions with my chronic intestinal health conditions when I have implemented the natural medicine Sherrlyn recommends. Consequently, if I do not take Sherrlyn's recommended supplements, I digress. That is how I know that it is working. Additionally, Sherrlyn's secretary, Natalie is extremely kind and patient as she provides great customer service to their clientele. Both Sherrlyn and Natalie's customer service is resfreshing. I am extremely thankful for everything "The Center" has done for me and my health, and I look forward to continuing to work with this organization." - Greg O'NeilREAD MORE REVIEWS

“In the nearly 2 years I have been getting advice & products from Advanced Nutrition I have never been disappointed. I came in at a time most would have told me to go to the ER. I never did need to go to the ER with what I was dealing with – and my health improved by leaps and bounds. Sherrlyn is knowledgeable, caring, sensitive and respectful of people’s financial situation, too. Going there changed my life!!” - S.A.READ MORE REVIEWS
SHERRLYN IS AMAZING!
Sherrlyn helped me deal with stomach pains that I had for 5 plus years. Many doctors’ specialists and alternative therapist couldn’t help me or offer suggestions. Sherrlyn reviewed my tests and really listened to me and offered a change in my diet as a solution. I thought I was healthy eating gluten free and lots of fruit. Within a month of using her suggestions I was 80% better. Within 3 months almost 100%. Now 18 months later I can’t imagine going back to eating my old way. Thank you! - Elissa KennedyREAD MORE REVIEWS

My experience with advanced nutrition was better than 5 star..! I was beyond surprised at the depth of knowledge that CNC Christmas-John has. I came to her with a highly complicated issue that my primary care doctors were lost with, and it appears we are on the right track. NEVER overlook what nature has to offer when administered by a professional like Mrs. Christmas- John…..! A two thumbs up from someone who has been around a bit…..! - Mark T.READ MORE REVIEWS
