MAG is a health service consulting company and is owned by the Michigan State Medical Society, AP Capital and approximately 250 Michigan physicians.

MAG was formed through the merger of Michigan Medical Advantage (MMA) and Winchester Consulting (WC) in 1998.

The healthcare market continues to change today, and so do our clients' needs. MAG's service offering has evolved in response.

MAG has expanded its services to help healthcare providers manage the demands being placed on them by the expanding role of information and technology in the delivery of health services and the evolution of health service financing mechanisms.
