The University of Michigan is home to one of the largest health care complexes in the world and has been the site of many groundbreaking accomplishments and technological advancements in healthcare since the Medical School first opened its doors in 1850. Today, UMHHC continues to be on the cutting edge of research and patient care and the U.S. News & World Report Magazine consistently ranks UMHHC within the top fifteen in the nation.

The Plant-Hospital Maintenance (PHM) Department supports this effort by maintaining the Hospital’s physical environment and provide maintenance services towards the delivery of quality healthcare and public service. We serve as a direct resource to the Hospital in providing a safe, functional, supportive, and effective environment for patients, staff members, and individuals who come to our hospital facilities. We also exist as Plant’s largest Service Level Agreement (SLA) with over 135 employees, including collaborative support from several other Plant Departments. We strive to exist as the “Employer and Provider of Choice” and execute “Best in Class” initiatives.
