It is the oldest formally established organization of Bolivian immigrants in the USA. An accomplished Bolivian immigrant from Cochabamba of this diaspora was Rosario "Charito" Anaya who was instrumental in establishing in San Francisco the Mission Language and Vocational School (MLVS), a vocational school with its mission of providing vocational training to new immigrants from Latin America. MLVS started at the Centro Social Obrero building in San Francisco (where it currently continues) teaching new immigrants English as a second language and providing secretarial, medical assistant and culinary arts training as well as providing their students employment in banks, hospitals and restaurants. Ms. Anaya was formally recognized as a model citizen by the City of San Francisco.
