Every coach on this page is the same person who'll teach your kid a jab step on Tuesday and text you a video of their progress on Friday. The Mundelein staff isn't outsourced — it's homegrown, MHS-tied, and accountable.
Coach Reilly answers every parent email himself. He sat in your seat in 1998 — same gym, same hallway, same dream. Now he runs the whole pipeline.
Coach Reilly grew up two blocks from MHS. He played four years of varsity, captained his senior team, and then coached at every level on the way back — Park District clinics, freshman, sophomore, and 14 years as the MHS varsity assistant under Coach Hellinger. He took over the Jr. Mustangs in 2019.
His philosophy is the same one MHS varsity has run for two decades: five-out motion, switch everything on defense, sprint in transition, never lose your composure. Every Mustang from 5th grade up learns this. By 9th, the system is muscle memory.
Off the floor, he runs the program like a small business — payments, schedules, gym leases, parent calls. If something goes wrong, you talk to him. Not a board. Not a chain of voicemails.
Six head coaches, six assistants. Eleven of twelve are MHS alumni or active high school staff. Every coach has played, coached, or both — at the level your kid is being prepared for.
Played D2 ball at Lewis after MHS. Coached 8th grade Mustangs since 2017 — eight straight tournament finals appearances. Runs the same offensive concepts the MHS sophomore team installs in fall.
MHS All-State guard and girls varsity head coach since 2018. Three regional titles. Direct pipeline — every girl on her 8th grade team has been on her freshman roster the next year.
Plays in the same fieldhouse he plays Tuesday-night pickup — and runs MHS sophomore team practices on Mondays. Specialty: building shooters. Eight of his 7th-graders shot above 35% from the corner last season.
Played 4 years of D3 at North Central, two-time team captain. Took the 7th-grade girls to back-to-back state qualifying tournaments in '24 and '25. Practices are tough; her kids love her anyway.
The bridge from Park District rec leagues to travel. Runs both 6th grade boys and girls teams — same drills, same playbook, twice a week. Specialty: turning first-time players into confident competitors in one season.
Old-school by choice. Spends the first eight practices on stance, footwork, and pivots. The 5th grade Mustangs are not the loudest team in the gym, but they almost never turn the ball over. Parents call him "Coach Pat" — even other coaches.
Four convictions every Mustangs coach signs onto. Read them before tryouts — if they don't match how you'd want your kid coached, this isn't the right program. We'd rather you know that now.
Talent is unevenly distributed; effort isn't. We coach hard, we celebrate hustle, and we bench the kid who walks back on defense — even if she's the best scorer in the gym.
Pivot foot. Triple threat. Two-hand chest pass. We will spend an entire practice on stance if we have to. The 14-year-old who can pass with both hands wins more games than the 14-year-old with a step-back three.
What you learn at Jr. Mustangs is what MHS varsity runs. Same terminology, same actions, same defensive principles. By 9th grade, our kids aren't learning a system — they're refining one.
We text parents progress notes. We answer calls on Sundays. We celebrate report cards. If a kid needs a ride, a meal, or a sit-down — that's part of coaching. The Mustangs aren't a program you join; they're a family you're already part of.
