We are thrilled to welcome Sue Dorsey back to Gates Family Foundation in her new role as Chief Operating Officer/Chief Financial Officer. 

Sue returns to the Foundation with deep roots in our community and a long history of leadership that has helped shape who we are today. From 2016 to 2023, she served as Senior Vice President for Finance, Administration, and Impact Investing, playing a pivotal role in strengthening our organizational infrastructure, modernizing finance and operations systems, and helping build and steward robust impact investing portfolios. Her work during that time laid lasting foundations that continue to support our mission and impact. 

Reflecting on Sue’s impact during her earlier tenure, Tom Gougeon, President of Gates Family Foundation, shared: 

“Sue has been an amazing leader and thought partner. During her tenure, she helped completely overhaul the operating side of the Foundation and was instrumental in building a significant impact investing program. Throughout it all, she was an extraordinarily generous, thoughtful, and committed teammate.” 

Since leaving Gates Family Foundation, Sue has continued to bring her values‑driven leadership to the field, most recently serving as Chief Operating Officer for iAlumbra, LLC, the family office of Christy Walton, where she supported business strategy, strengthened operations, and built community across a diverse set of mission‑aligned entities. With more than 25 years of experience across foundations, family offices, and global nonprofits, Sue brings deep expertise in finance and operations, impact investing, strategy, and governance—along with a collaborative spirit and commitment to aligning values with action. 

We are excited to welcome Sue back to the Gates Family Foundation and Colorado’s philanthropic community and look forward to the insight, experience, and partnership she brings to this next chapter. Please join us in welcoming Sue back to the Foundation.
