The UMCNO Companion App is designed to support UMCNO staff, faculty and medical staff, residents and fellows, medical, nursing and associated health students in navigating the new UMCNO. It contains helpful maps, phone numbers, departmental resources, and a special section on The Joint Commission preparation. All eligible individuals are expected to download it, become familiar with it, and use as needed. We hope you find it helpful, and welcome your suggestions for improvement and for additional tools to be added in the future.
