Alexander J. Rinehart, MS, DC, CCN, CNS

Dr. Rinehart grew up in a single parent family and experienced firsthand the effects of food insecurity. He has watched close family members be grossly mismanaged by the existing health system and is determined to “lead the change”, one patient at a time. He has devoted his life and career to the study of functional health and advanced laboratory testing & analysis.

Dr. Rinehart began his education with a self-designed major in “Social Issues and Health” and co-authored a textbook chapter in the Handbook of Diet, Behavior, and Nutrition entitled “Dietary Behavioral Mechanisms in Times of Economic Restraint”. His background in sociology gives him a unique perspective on health and disease by helping him appreciate the web-like interactions of the human body and a focus on the upstream “causes” of dysfunction in the human body, not the downstream “effects”.

    Amy Medling, CHC

    Amy Medling, CHC, is the founder of PCOS Diva.com, an online resource dedicated to helping women understand and manage the symptoms associated with Polycystic Ovarian Syndrome (PCOS). She studied holistic nutrition at the Institute of Integrative Nutrition and is a Certified Health Coach. Diagnosed with PCOS 12 years ago, Amy thought she found relief when her doctor prescribed Metformin and the birth control pill. Instead of relief, she felt trapped inside a body that rejected these artificial treatments. This is when her Diva journey began. She moved from a “why me?” self-pity state to a place of empowerment that ultimately led her to becoming a “PCOS Diva”. Her dedication and research produced a proven treatment plan that uses whole food, natural remedies, supplements, exercise, self-care, positive thinking and stress reduction to relieve and control PCOS symptoms.

    Amy’s goal is to coach other women with PCOS, to find a body, mind and spirit balance that will have them proclaiming, “I’m a PCOS Diva too!”
