Paustian IBD Center Faculty & Staff
The IBD Center is staffed by four gastroenterologists and three colorectal surgeons who have clinic hours in the center alongside each other. Our team also includes two IBD nurse case managers, one registered dietician, one specialty pharmacist, one gastropsychologist, two medical assistants and two medical receptionists. Sponsored- and investigator-initiated studies are supported by a divisional research group consisting of a regulatory specialist and three full-time research nurses.
