When I was first diagnosed I contacted Doctor Woltering with questions about my disease. He gave me his mobile number and said call any time. I said I wouldn't dare as I live in Australia and might wake him at 4am by mistake, but he said that wouldn't be a problem. I am so grateful for the time he took to help me in those early days.
Doctor Woltering is held in very high regard by the ACOR Carcinoid members. In the two years I've been on the ACOR Carcinoid list I have heard many patients say that Kenner will perform debulking surgery when other centres have sent the patient away.

Best of luck to your father, Annie.
