Built by greats: Some Key Mentors Behind JMDII
Greatness is never built alone.
JMDII isn’t just a reflection of my journey — it’s forged from the wisdom of legendary coaches who molded me into the athlete and leader I am today. From NFL All-Pros to powerhouse D1 minds, these men helped shape my mindset, my standard, and my system. Their fingerprints are all over JMDII — and their legacy lives on through every athlete who steps inside this academy.
Kalen DeBoer
Championship Mindset & Master Execution
1X NCAA National Championship Appearance| Current Head Coach at The University of Alabama
Coach DeBoer guided me during the final years of my collegiate career. His precision, preparation, and championship culture were different.
He taught me the power of micro-details — how greatness isn’t just built in games or workouts, but in the unseen hours. The unseen actions. His ability to create systems that win deeply influenced how I built JMDII.
Coach Deboer’s Standard of Excellence Lives inside JMDII as it forever lives in me.
Rod Perry
Elite Wisdom & Total Accountability
2x All-Pro NFL Cornerback | 23-Year NFL Coaching Veteran
Coach Perry was my “Mr. Miyagi.” He’s mentored me for over 6 years and has helped reshaped the way I thought about performance and life.
“Sacrifice for what you want… or what you want becomes the sacrifice.”
“In the game of football, and athletics, Your body is your business. Treat it like your greatest asset.”
These weren’t just lessons — they were code. He drilled into me the mindset of total ownership, discipline, and accountability.
A huge part of JMDII’s Mindset Mastery program is rooted in the values he taught me — values that continue to guide every move I make, and that I wish to pass onto as many young athletes I can to help to help guide them on their journey’s to football success.
Ron Mckeefery
Master of Performance Systems
2x National Strength Coach of the Year | NFL, Collegiate, & Olympic Level
Coach McKeefery is a global icon in the world of strength and conditioning. His systemized approach to training taught me key details in developing athletic performance— with relentless precision.
Training under him gave me the blueprint for sustainable, elite development. The structure, recovery systems, & the relentless standard — all live inside of JMDII.
He taught me that excellence starts with the smallest details. And those details? They change everything.
JD Williams
The Standard of Consistent Greatness
First-Round NFL Draft Pick | Played in x4 Super Bowls With Buffalo Bills | Fresno State Legend
Coach JD was with me every day throughout my D1 career. From meeting rooms to the field, his messages and standards never wavered:
“Winners win. Because Thats What Winners do.”
This means that Winners win Not by accident — but because it’s who they are.
This was a big one that was laid onto me from Coach JD. His mindset became my mindset. Consistent excellence in everything — from how you prep, to how you move, to how you recover. If you’re a winner, you win in all that you do. It’s a standard of excellence.
That standard is now the backbone of JMDII. Not just “sometimes elite” — but elite, always. Because that’s who you are. And that’s what it takes.
Jeff Tedford
Discipline is the Difference
Winningest Coach in Cal History | Retired Fresno State Head Coach
Coach Tedford was my first D1 head coach and the one who lit the fire for how I approached this game at the Division 1 Collegiate level.
“How you do anything is how you do everything.”
He taught me that details aren’t optional. That your process is your outcome. His leadership deeply shaped my structure, my planning, and the intensity I now bring to every athlete I help through my guidance.
The discipline-first foundation of JMDII? That comes from Tedford.
🔱 A Legacy Built from Central Valley Love
JMDII wouldn’t be what it is without the countless coaches and mentors throughout the Central Valley who believed in me and poured their knowledge and experience into me.
If you coached me, spoke life into me, or challenged me to grow — your impact is here. It’s in every program, every rep, every athlete who trains under JMDII. I’m Forever Grateful.
