The 2016-17 season was Mark Hill’s 7th season back as the Aztecs Head Coach after a 15 year absence. It was an historic season last year for Esperanza which finished 30-3, ranked 3rd in the county the entire season, won back-to-back League Championships in the tough Crestview League, won the So Cal Regional State final and went on to Sacramento and claimed the Division II  State title. Mark was honored as Coach of the Year by both the OC Register, the OC Optimists (which operates the OC All Star game) and also was named Division II State Coach of the Year.


In Coach Hill’s first head high school coaching job, he took a struggling Esperanza program (which had not been to the play-offs the previous 7 seasons) and turned it into one of the best programs in the county.  During his tenure from1988/89-1995/96, he led the Aztecs to the play-offs 7 straight seasons, won 3 league championships in his last 5 years including his last team, which finished 25-4 and ranked third in Orange County. Coach Hill is the winningest coach at Esperanza with a career 267-155 record, was selected league coach of the year six times, and was honored by being selected the head coach of the North team in the 1995-96 Orange County All-Star game.


Mark was out of coaching for a year working and receiving his Master’s Degree from Azusa Pacific University, and then joined the staff at Orange Coast College in 1997/98.  He was an assistant for 2 years, helping Coast qualify for the play-offs both years. Coach Hill was then selected as head coach at OCC in 1999/2000 and served in that capacity for two seasons. Again, Mark helped lead the Pirates to the play-offs both years. 


 Coach Hill then became the head coach at Laguna Beach HS from 2003-2005, where he took over a poor program that had only won 2 league games in the previous 4 seasons. In Mark’s two seasons he led them twice to third place finishes in league qualifying for the play-offs where they lost both years in the second round of the CIF play-offs. In fact his second season the team finished 17-11 which was the 7th best season in the 50 year history of Laguna Beach.


Coach Hill has been a teacher at Esperanza his entire teaching career of 29 years where he currently teaches Physical Education.
