I. I am the Medical Director for the Inflammatory Bowel Disease (IBD) Program at Yale University. I treat patients in three locations - Temple Medical Building, Yale Health, and Yale-New Haven Hospital. The Inflammatory Bowel Disease Program is a multi-disciplinary program with medical, surgical, pediatric, pathology, and radiology specialists all participating in the care of our patients. Our program offers specialized nursing care and education with a nurse practitioner who specializes in patients with inflammatory bowel disease as well as an ostomy nurse who specializes in ostomy and wound care. Patients are self-referred as well as referred from other physicians. To schedule an appointment, please call 203-785-4138 (Temple Medical Building) or 203-432-0335 (Yale Health).

In addition to multi-disciplinary patient care, our program offers opportunities for patients to participate in research studies that evaluate mood disorders in IBD; treatment choices in IBD; and participation in multi-center new drug treatment protocols.

II. I am the gastroenterologist for the Hereditary Hemorrhagic Telangiectasia (HHT) Center at Yale . I evaluate and treat patients with HHT who have gastrointestinal bleeding and other gastrointestinal related problems. To schedule an appointment, please call Katharine Henderson at 203-737-5395.
