Board Members

Improving the Mosaic experience and focusing on community needs

Mosaic is governed by a volunteer, patient-majority board of directors with representatives from Crook, Deschutes and Jefferson Counties. Board members donate their time and talent to help Mosaic continually improve our access, quality and delivery of care in Central Oregon.

Mosaic accepts applications for board members and board committee members on a rolling basis.
