Leonel Castillo is a former controller for the City of Houston, and a commissioner for the U.S. Immigration and Naturalization Service. Mr. Castillo was the first Mexican-American ever elected to citywide public office in Houston. He earned a reputation as a fiercely independent Controller, and was known for saying that the Controller “needs to be an independent cuss” to do the job properly. Mr. Castillo has also been an active champion for expanding leadership and economic opportunities for Mexican-Americans.
