Following her graduation, she returned to California and taught fourth and fifth grade, later becoming headmistress of a school in Manhattan Beach[1][7] and worked as the director of operations for the Israeli-American Council.[1]
Streit described her push to activism as a result of Israel's portrayal in American media and growing Anti-Zionism, along with the role of teacher's unions.[7]
In 2009, Streit joined PragerU, a non-profit promoting conservative and capitalist viewpoints. In 2011 she was promoted to its Chief Executive Officer position.[3][7]
Streit has overseen PragerU's vision of "edutainment", focusing on cartoons and five-minute YouTube videos to promote the conservative and pro-Israel point of view on various issues.
Streit has criticized the teaching of climate change in schools, including in Florida.[8][9][10] She has overseen the expansion of PragerU teaching material to Texas schools.[11]
In August 2025, Streit interviewed Hungarian Prime Minister Viktor Orbán on Hungary's relationship with the European Union.[12]
