Run Game Coordinator, Baltimore Ravens
Juan Castillo most recently served as defensive coordinator for the Philadelphia Eagles of the National Football League from February 2, 2011 to October 16, 2012.
Juan played college football at Texas A&I as a linebacker, and he played professionally for the San Antonio Gunslingers of the United States Football League from 1984-1985.
Castillo was the defensive line coach for Texas A&M University-Kingsville from 1982-1985 and from 1990-1994 he was the offensive line coach. Four offensive linemen he coached ended up in the NFL: Jermane Mayberry, Jorge Diaz, Kevin Dogins and Earl Dotson.
The Philadelphia Eagles hired Castillo as an offensive assistant in 1995 under Ray Rhodes. In 1996, the Eagles drafted Jermane Mayberry, an offensive lineman Castillo coached at Texas A&M University – Kingsville, in the first round of the 1996 NFL Draft. Castillo was promoted to tight ends coach in 1997, and switched to coaching the offensive line in 1998. When Andy Reid was hired as the head coach of the Eagles in 1999, he retained Castillo on the coaching staff, where he continued to coach the offensive line for twelve more seasons from 1999-2010.
Castillo became the defensive coordinator for the Eagles following the firing of Sean McDermott on February 2, 2011. The hiring was met with surprise by players, fans and members of the media primarily because Castillo had not coached the defensive side of the ball since he was at Texas A&M University – Kingsville in 1989.
Castillo is married to his wife, Zaida, they have four sons: Gregory, John, Andres and Antonio. Gregory is currently a cornerback at the University of Iowa, and John is currently a distance runner at Villanova University.
