Our program offers specialized nursing care and education with a nurse practitioner, Nana Bernasko, who specializes in patients with IBD as well as an ostomy nurse who specializes in ostomy and wound care. Patients are evaluated daily at 40 Temple Street, Suite 1A in New Haven. Patients are self-referred as well as referred from other physicians. To schedule an appointment, please call 203-785-4138.
