In addition, our center's director, Russell Cohen, MD, works with an advanced practice nurse (APN) who is trained in IBD care in the outpatient setting. The APN manages and treats inflammatory bowel disease in collaboration with the physicians. APNs see established patients independently in the clinic setting and are able to order necessary lab work or diagnostic testing and order prescription medications.
