ONTARIO — As a larger than life 6-foot-6, 260 pounds, Ontario High head football coach John Kusleika seemed like he could overcome anything.
Unfortunately, that was not the case.
Shortly after beginning chemotherapy treatment for stage 4 cancer, Kusleika died Saturday, March 9. He was 55. He leaves behind a wife and three children.
“He had been at school up until the first chemo treatments 2 ½ weeks ago,” Joe Szczepanski, Ontario’s athletic director and assistant football coach, said Monday. “He was in great spirits, talking about finishing chemo and coming back to coach.”

Ontario held a celebration of life at the football field for Kusleika on Tuesday evening where his former players, colleagues and family members placed mementos, balloons and battery-operated candles on the 50-yard line and several people spoke about him.
“Coach K was an amazing guy,” said Adrian Ochoa, who played quarterback for Kusleika before graduating in 2020 and later served as a quarterbacks coach. “It was way more than a coach-and-athlete relationship. I viewed him as another father figure in my life. He really helped you develop right from wrong, to be caring, respectful and loving.”
Kusleika graduated from Redlands High in 1986, then went on to play tight end at the University of La Verne.
It was there that he met Chris Kimberly.
“He made it easy (to become friends), he was approachable,” Kimberly said. “He could get people in a group and make it work.”

Kusleika was hired by the Chaffey Joint Union High School District as a teacher and head football coach at Montclair in 1999, beginning a 25-year run as a teacher in the district. The district orientation meeting is where he met Szczepanski, who was hired as a teacher at the same time.
Szczepanski told Kusleika he had some coaching experience. The next day, Kusleika called him and asked if he wanted to be part of his coaching staff.
Kimberly came to Montclair the next year, thanks to Kusleika.
“Things didn’t work out (at a previous coaching stop), and he was the first phone call I made,” said Kimberly, who currently coaches at Etiwanda. “I have him to thank (for being in the district). It’s ‘let’s see if I can get you here.’ He’s done that for several people.”
After three years at Montclair. Kusleika left to take another head coaching job in the district at Alta Loma. The first year at Alta Loma he coached Eric Weddle, who went on to a 14-year NFL career in which he was named to the Pro Bowl six times and to the All-Pro Team twice.
At Alta Loma Kusleika had a profound impact on many athletes, including Greg Keele who played linebacker there before graduating in 2006.
“He was an avid student of the game, a careful and thoughtful game planner and one of the best organizers of a football program I have met to date,” Keele said on a podcast he recorded after learning of Kusleika’s passing. “Thank you coach for helping me become a man.”
Keele had many crises he went through in his personal life and Kusleika was there to help him through them.
“He was a big teddy bear. He knew he was naturally a (physically) dominant person. Nobody could question that,” said Keele, who later coached under Kusleika and who is currently an assistant coach at Vista Murrieta. “You get the impression he was a big tough guy. The truth was he was an academic. Conversations I had with him were something I would get from a Harvard geek. We would hang out on Sundays and talk coaching philosophies. He loved to learn.”

Kusleika eventually resigned at Alta Loma and served as an assistant coach at Redlands East Valley and Rancho Cucamonga for a few years before taking the Ontario job in 2014.
He did not have a lot of on-field success at Ontario, making the playoffs only once in 10 years, but he was credited for constantly adjusting his offensive and defensive schemes to adjust for the strengths of his players.
“The great thing about John was he was going to give 100 percent, whether it was an 0-10 or a 10–0 team,” Szczepanski said. “Obviously going against better talent, it could turn south. We’re going to fight our fight. You can’t say enough about the commitment.”
At the end of the celebration Tuesday, the scoreboard clock counted down from 10 minutes, signifying the 10 seasons he coached at Ontario. The 10 seasons tied him for the longest football coaching tenure at the school.
“Success comes about in different ways in different places,” Szczepanski said. “He had a passion about the school. He was a well-loved man on campus.”
