Nancy Keer Armstrong

I work as a freelance Chief of Staff and strategic advisor, partnering with founders, executives, and leadership teams to turn big ideas into actionable plans. I specialize in aligning strategy, operations, analytics, and marketing so organizations can scale efficiently and make smarter decisions.

As an advisor with AdvisoryCloud and a member of multiple boards, I enjoy mentoring startups and guiding leadership teams through growth, change, and innovation. My approach combines analytical thinking with hands-on execution, helping companies navigate complex challenges while staying focused on their long-term vision.

Earlier in my career, I co-founded Refinext, an electronic medical device recycling and reporting company dedicated to sustainability and precious-metal reclamation. Building and eventually transitioning that business taught me invaluable lessons about entrepreneurship, partnerships, and resilience. I also spent several years at Sprint in corporate brand marketing and business development, where I strengthened brand identity and built key business relationships.

I’m passionate about helping organizations grow with purpose, empowering leaders, and building systems that create lasting impact.
