Mercy Corps, with funding from Linked Foundation, piloted and launched a micro-pharmacy program, Tiendas de la Salud (TISA). Since its inception Greg sat on TISA's advisory board and acted as their unit-economics expert. Today the micro-franchise network of 50 health stores supplies high-quality, low-cost medicines to 88,000 people in rural areas of Guatemala. Recently, a key private-sector partner - Farmacias de la Comunidad - will expand TISA to an additional 500 stores in other rural areas of Guatemala that are expected to reach more than 450,000 people.
