The 6-4.5, 240-pounder has started for two years on both sides of the ball and has been a big part of the Crusaders' success the past two season.
In their win over Beaverton (Ore.) Aloha, he was big on offense, with a couple of touchdown grabs, and defensively, helped Jesuit limit five-star running back Thomas Tyner to less than 100 yards, his lowest output of the season.
"I'm learning just a lot from those guys," said Mondeaux. "These guys keep their heads up the whole time, don't talk to the refs, don't talk to the other team. They just lead us in games, lead us in practice."
Mondeaux doesn't have any offers yet, but a number of schools have expressed interest in him.
Which side he'll play on remains to be seen, but his heart is on offense.
"I haven't heard much about which side schools like me at, but I think I can play a lot of different positions," said Mondeaux. "I like tight end, but I could be either a tight end or a defensive end. As a tight end, I think it would be good to move me inside because I can run block really well."
Mondeaux said he's hoping to get to about 250 by the time he gets to college, but thinks he's done with the height.
"I don't think I'll grow anymore, maybe an inch more, but I want to maybe gain a few more pounds of muscle," said Mondeaux.
Mondeaux said he was thrilled with Jesuit's performance against the vaunted running game that Tyner spearheaded, but wasn't surprised.
"We take a lot of pride in doing our job and we just made sure people weren't trying to do too much and that we stuck with our plan," said Mondeaux. "And then offensively, I think we started changing up more of the plays, instead of running right up the middle, as we looked at their defense, we knew we'd have to score big, and then our defense stepped up. I think we'll keep the ball rolling."
