Sastha Tamil Foundation (STF) is a non-profit organization focused on bringing communities together for charity and service, with a goal of promoting volunteerism as a humanitarian change overall. To impart the Tamil culture, values, literature, and charity as a way of life, STF was founded in 2010. As a result, one of STF's main objectives is to promote Tamil language and culture to children in the community. Plano Tamil School (PTS), which is now a subsidiary of STF, was started in 2001 to teach Tamil to children using a structured curriculum.
