She is currently on the board and audit committee of First Solar, Inc. (Nasdaq: FSLR).

Katy is a natural coach and leader whose style is anchored in her genuine enjoyment of collective problem solving and decision-making.  A strategic and systems thinker, Katy thrives in high-stakes environments when circumstances are changing or ambiguous, multiple stakeholders are involved, and competing short- and long-term goals are at play.

Based on the breadth of her experience and her direct yet diplomatic approach to resolving complex challenges, Katy was selected by her partners to serve two terms on both the Deloitte U.S. and Global Boards of Directors. Her tenure on these boards was punctuated by planned and unplanned chair and CEO successions, as well as multiple business crises including a cyber incident, significant litigation and domestic and global regulatory matters. Board leadership roles included serving as US Board Vice-Chair, Chair of the Global, Governance and Global CEO/Chairman Evaluation Committees and member of the US Chairman/CEO succession, Governance Modernization, Strategic Investments, Finance & Audit, Risk, and Earnings and Benefits committees.

Katy is passionate about organizations and industries with bold, transformative missions related to life sciences, healthcare, the environment and education.
