About Corporate Compliance

The Medical College of Wisconsin has a strong and abiding commitment to ensure its compliance with the regulatory requirements that govern our missions of Education, Research, Patient Care, and Community Service.

The main function of the Corporate Compliance Program is to create a comprehensive strategy to ensure the College is consistently complying with the federal and state regulations relating to our missions. The Division of Corporate Compliance has four offices that assist with this function: The Clinical Compliance Office, the Internal Audit Office, the Research Compliance Office and the Risk Management Office.
