Who serves as the board chair for the US Olympic and Paralympic Committee?

The board chair for the US Olympic and Paralympic Committee is Susanne Lyons. In her role, she provides leadership and oversight for the committee's strategic direction and governance. Lyons has had a significant impact on the organization, especially in areas such as athlete advocacy and organizational development. Understanding her contributions helps to appreciate the importance of leadership in promoting and enhancing the mission and goals of the committee.

Other individuals mentioned in the options have distinguished roles within the Olympic movement, but they do not hold the position of board chair. For example, Sarah Hirshland serves as the Chief Executive Officer of the US Olympic and Paralympic Committee, Andrew Parsons is the President of the International Paralympic Committee, and Trischa Zorn is a notable Paralympic athlete and advocate. Each of these individuals play vital roles within their respective areas, but it is Susanne Lyons who fulfills the critical position of board chair.
