Varsity Head Coach Luis Casillas


Coach Casillas has been coaching competitive soccer since 1997. Coach Casillas was recruited to coach by Coach Frank Zimmerman at the Soccer Club of Oceanside. First recruited as a trainer, Coach Casillas soon took over his first team and took that first group of boys to the Premier level in the Presidio Soccer League from AA-B in three years. Several of those boys went on to play in local Community Colleges, CSUs, and Division 2 programs. Coach Casillas went on to Coach another team from AA-B to Premier in the same amount of time, and that team boasts a Division 1 college player along with several community college players. Coach Casillas then moved to the Temecula Valley Soccer Academy Hawks where he coached several boys teams and worked the Hawks recreational and competitive team camps. Upon his return to the SCO, Coach Casillas has focused on coaching girls and currently coaches the 2003 Girls Black SYL and the Girls 2006 Black SYL team in Flight 2 of SDDA. The 2003s are current league champs and the 2006s are headed to Florida for 2019 SYl National Finals!
Coach Casillas' high school career started at Oceanside High as the Boys Freshman Coach/Varsity assistant for two years. Coach Casillas then moved to the girls side and was the Assistant Varsity Coach and JV head Coach for two years. His career continued for one season as the Head JV Boys Coach and Varsity Assistant at Vista High School. Most recently, Coach Casillas was the Head JV Coach and Varsity Assistant at Rancho Buena Vista High School, where the Longhorns were back to back League Champions and went to the CIF State playoffs. The 2012-2013 Wildcats set every (good) school record and were selected for the first time to the CIF playoffs! The 2013-2014 team also broke records and won the school's first CIF playoff game and were defeated in the quarterfinals. The 2014-2015 also set high marks, winning the school's FIRST Tournament Championship at the Lady Vaqueros Tournament and then again, barely losing in the CIF Quarterfinals.In 2018 the Wildcats won the first Girls Soccer Banner in school history by winning the Avocado East League and also were Runners-Up in the CIF Division 2 Finals. The Wildcats have progressed to the CIF playoffs every year under Casillas, and this season hope to be no different in the competitive Division 1.


Coach Casillas' focus is on developing the entire Girls Soccer program at ECHS, and enjoys players develop into Varsity-level players whether they walk on as such or spend time through all three levels offered.

Coach Casillas is a Spanish Teacher at César Chávez Middle School where he will help continue the Two Way Bilingual Immersion Program and holds: a Master's Degree in Spanish Literature; A Single-Subject Teaching Credential in Spanish with a Supplemental Authorization in French; a Multiple Subjects Teaching Credential; and a Bachelor's Degree in Spanish with a Minor in French.
