Yoko Shimomura: Executive Leadership on Demand

Strengthening Systems, Strategy, & Culture for Lasting Impact

About Me

I am a seasoned executive with over 20 years of experience leading operations in the corporate, philanthropic, and nonprofit sectors. My background spans the full spectrum of COO and executive leadership, including strategy, finance, HR, IT, grants and contracts, facilities, and communications.

If it needs to be streamlined, rebuilt, or handed to the right talent, I’ve probably done it.

Today, I partner with mission-driven organizations as a Fractional COO, offering both strategic and operational leadership without the full-time price tag. I step in as Interim, serve part-time, or lead high-impact projects, such as strategic planning, talent management, or system overhauls.
