Dr. Datis Kharrazian is a one-of-a-kind clinician whose passion for research and evidence-based medicine led him to spend years in laboratories such as Immunosciences Lab in California and Cyrex Labs in Arizona, as well as in universities such as Harvard Medical School, Loma Linda University School of Medicine, Bastyr University California, and Lincoln College of Professional, Graduate and Continuing Education. In these centers of study and research he used his own time and resources in order to get to the root causes of thyroid and many endocrine and autoimmune disorders.
