Chief of Staff vs Executive Assistant: The Real Difference
The two roles are often confused because both sit close to the executive. What separates them is not seniority, it is the unit of work.
An Executive Assistant is accountable for the executive's time and coordination, and a great one is indispensable. A Chief of Staff is accountable for the organization's follow through: the priorities, the cadence, the cross functional work that has no natural owner.

When a leadership team needs a Chief of Staff
The signal is rarely growth alone. It is the gap between what leadership decides and what the organization does. When priorities multiply, when the same issues return to the same meeting, when initiatives depend on one person's memory, the role pays for itself.
The path from support to strategy
Many Chiefs of Staff come through executive support, and that background is an advantage rather than a limitation. It builds judgement about people, discretion, institutional context and an instinct for what is actually urgent. What changes on the way to Chief of Staff is scope: from managing an executive's day to shaping how an organization operates.
