Sandee Minovi
Sandee Minovi brings more than 20 years of strategic leadership to the table, dedicated to operationalizing complex health and development goals on a global scale. As the 'operational heart' of large-scale initiatives, she ensures that every project—no matter how geographically dispersed—is set up for success from the start.
Throughout her career, Sandee has managed multi-million-dollar portfolios around the world, but her drive for this work is deeply personal. Her dedication to marginalized communities was first sparked while working with street children in Guadalajara, Mexico, and was later galvanized by her own experience surviving a life-threatening pregnancy complication — a moment that underscored the vital importance of resilient, accessible health systems. Whether she is navigating the financial nuances of a major grant or mentoring a global team across 20+ countries, Sandee’s approach is rooted in partnership and a deep commitment to health equity. She has spent decades building trusted relationships with partners and funders, always with the goal of making operational processes feel seamless so that technical experts can focus on what they do best.
Sandee holds an MA in International Development Studies from George Washington University and is always looking for modern ways to work smarter, recently earning her PMI certification in Generative AI for project management. When she isn't streamlining global operations, she is a dedicated advocate for inclusive leadership and a firm believer that the best results come from a collaborative, high-trust team environment.
