Chapter Medical Advisory Committee
The Crohn's & Colitis Foundation, Northwest Chapter is proud to have two robust committees of healthcare providers serving on its Chapter Medical Advisory Committees (CMACs), led by chairs Michael Chiorean, MD in Seattle and Nir Modiano, MD, PhD in Portland. These individuals provide Foundation staff with invaluable support including insight on issues that are important to their patients, directing their patients to take advantage of the Foundation's services, and act as local liaisons for planning events in their communities. The chairs ensure that value is returned to members in the form of education opportunities, public recognition, and ongoing engagement and appreciation. 

The Northwest Chapter would like to recognize the following individuals currently serving on our CMAC and thank them for their true dedication and support of the Foundation's mission:
