Current Board of Directors

The Shareholders of GSEP elect a Board of Directors to lead the organization. The GSEP Board consists of one Board member for every four Shareholders at a site. However, each Board member represents all Shareholders not only those at his or her own site. This provides a balance between site specific concerns and organizational concerns.

The GSEP Board elects a President, Vice-President, Treasurer, Secretary, and a Director of Medical Operations.

Medical Directors

We position a Medical Director at each facility with an overall Medical Director for all our facilities. Collectively, our Medical Directors serve on a Quality Improvement Committee dedicated to continually improving processes involved in treating patients in the Emergency Department. Focusing on the most up–to-date clinical information, the committee addresses such issues as patient satisfaction and quality of care.

Each site elects a Medical Director that is responsible for the daily operations of that site. The Medical Director works closely with the hospital’s Nursing Director to improve processes that effect ED function. Current site Medical Directors are:
