Vice President, Global Development Delivery Practice

Mariandrea Chamorro has 20 years of experience managing international development programs. She has provided oversight for the high-quality and compliant execution of large flagship USAID programs while contributing to business development. Chamorro’s areas of expertise include prevention of vector-borne diseases, infectious diseases, maternal and child health, and health systems strengthening. Her clients have included the U.S. Agency for International Development (USAID), the Australian Department of Foreign Affairs and Trade (DFAT), and the UK’s Foreign Commonwealth & Development Office (FCDO). 

As vice president of the Global Development Delivery Practice, Chamorro leads over 2,000 staff working in more than 50 countries on global health, climate and clean energy, governance, food security, and economic development programs.

Chamorro oversees project health and delivery performance, including financial performance and compliance with corporate and client requirements. Leading the interface with departments, she addresses operational complexities and optimizes the use of project management staff to do so. She ensures the application of project and program management best practices to manage scope, quality, budget, schedule, subcontractors, staffing, stakeholders, and risk in scope, cost, schedule and quality.

Chamorro directly oversees Abt’s flagship Local Health System Sustainability, President’s Malaria Initiative Evolving Vector Control to Fight Malaria (PMI Evolve) Project, and Health Electrification and Telecommunication Alliance programs.

In her previous role as regional vice president, Chamorro oversaw Abt’s programs in Europe, Asia, Latin America, and the Caribbean. She provided overall leadership, management, strategy, and vision for the assigned regional management unit with a portfolio of more than $35 million in annual revenue and a two-year pipeline valued at more than $250 million. Chamorro led and oversaw the development and implementation of a regional strategy and was responsible for the unit’s financial management. She ensured successful implementation and client satisfaction on programs and provided quality assurance to business development efforts in the region.

Before assuming that role, Chamorro was the deputy project director for PMI VectorLink, a $741 million project working in 25 countries in Africa, Cambodia, and Colombia to decrease the burden of malaria through vector control. She provided oversight and leadership to the Operations and Procurement and Logistics teams, and she managed the project’s 10 international partners. Chamorro provided senior-level management expertise and vision and served as a liaison to all Abt corporate departments. Under VectorLink’s predecessor project, PMI Africa Indoor Residual Spraying, Chamorro managed malaria prevention programs in seven African countries.

Before coming to Abt, Chamorro worked for the Millennium Challenge Corporation on Cape Verde and Mozambique compacts. She also worked for Chemonics International in the Latin America and Caribbean division and the International Health Group, managing USAID-funded economic growth projects in Peru and Bolivia.
