Chief of Staff

Chief of staff (or head of staff) is a leadership title with different meanings in civilian and military organizations. In civilian government organizations and businesses, a chief of staff is a primary aide-de-camp to an important individual, such as a president or leader of a large organization... In civilian organizations, a chief of staff provides a buffer between a chief executive and that executive's direct-reporting team. The chief of staff generally works behind the scenes to solve problems, mediate disputes, and deal with issues before they are brought to the chief executive.[1] Often a chief of staff acts as a confidant and advisor to the chief executive, acting as a sounding board for ideas. Ultimately the actual duties depend on the position and the people involved. https://en.wikipedia.org/wiki/Chief_of_staff
