Dr. Stengler misdiagnosed me with Hashimoto's thyroiditis, which is an autoimmune disease. I spent 7 months thinking I had this until I went to an endocrinologist who confirmed that the blood test he gave me clearly showed me I didn't have it. The scary thing is I think he purposely misdiagnosed me so that he could sell me his supplements. YIKES. When I confronted him about it he pretended that he never gave me that diagnosis, that I imagined it.... riiiiiight.
