Nelsa Curbelo

In 1999, Curbelo was elected to Ashoka as a Fellow.

On 16 April 1999, Curbelo founded the non-profit organization Ser Paz, in English "Being Peace," to help the city's youths and reintegrate gang members into society. Beginning in her resident barrio of Guayaquil, she established mediation workshops and small businesses to settle gang disputes and give their members employment. For the first two years of operation, Curbelo met with and heard the grievances of many Guayaquil youths. In 2006, the NGO began the "Barrio del Paz" program, which would cover 42 of the most violent and criminally active blocks in the city. Twelve small businesses, such as a print shop, salon, and furniture store, were established and staffed by mixed groups of youths from various gangs.
