Krista Boscoe

Senior Director, Recruitment and Community

As soon as she heard about AMIGOS in her freshman year, she wanted to go. She waited impatiently until she was 16 and then headed to Mexico in 1982 to work in latrine construction. To this day, she walks by bags of concrete at Home Depot with a well-trained desire to get some water and start mixing. The following summer, she went to Ecuador on a rabies vaccination campaign. While studying Sociology at UCSC, she returned to Ecuador in 1985 as field staff and then went back to Mexico in 1987 as the project director in Michoacan.

After college, she moved to Washington DC for two years. Her life took an unexpected turn when she moved to Seoul, South Korea for three months that became five years. Asia was a true revelation to her and she loved every moment. When she returned to the US, she came back to San Francisco to work in International Education. She is thrilled to come full circle and be back with AMIGOS on the West Coast.
