“The shear volume and rising care complexities of people with diabetes, and its related illnesses, are rapidly overwhelming our healthcare system as its designed. It’s also causing significant suffering to our patients. After many years of medical practice, it was obvious to me that medications and shots alone aren’t an adequate solution. We wanted to provide this top-notch resource center with a different approach in order to help providers and patients tackle the problem of diabetes and obesity, and to hopefully re-create health for our patients.”
