Donald Berwick, MD, MPP, the departing CMS Administrator, brought his deep expertise and vision for health care improvement to all he did at CMS. We thank him for his leadership there, in particular the role he played in helping shape the Medicare Shared Savings Program, Accountable Care Organizations regulatory framework. Dr. Berwick has been a friend to medical groups and the high standards of care which they practice and espouse. While Dr. Berwick will be leaving the Federal health care stage, he will not be exiting from the arena and we wish him well.
