ABSTRACT A conceptual model for the design and implementation of effective social services for Latino older adult immigrants in the United States is proposed in this article. Built on the stage-of-migration framework (Drachman, 1992), the model presented shows how the premigration service experience of Latino older adults can be used as a basis for service design and implementation in the country of immigration. The case of Puerto Rican older adult immigrants is used to illustrate how the model can be applied to understand present service utilization and develop future programs that are useful and culturally sensitive for Latino older adult immigrants.
