What do I say about a doctor who may have saved my life

What do I say about a doctor who may have saved my life--not once, but on three different occasions? The first was when he insisted on my getting a colonoscopy, which disclosed three polyps that were potential cancers. The second was when he diagnosed a kidney failure and rushed me to intensive care just in time. The third was when he spotted a skin cancer while it was still in its early stages and could be removed before it became life-threatening. Dr. Schrader is a credit to his profession and a great human being. I count myself very lucky to have him as my primary care physician.
