The Person Behind The Training
Welcome!
My name is Joe Frederick — known by many as “Cojo.” I’m a lifelong athlete, coach, and mentor born and raised right here in Westchester County, driven by a passion to help young athletes discover real confidence, skill, and love for the game.
While I’ve built programs and guided teams to championship runs and individual honors, I still see myself first and foremost as a student of the game. I believe that if I expect my players to invest time and energy to improve, then I must do the same. That’s why I continually seek out new certifications, training methods, and coaching philosophies — leading by example and bringing fresh ideas back to every athlete I work with.
And although I’ve been fortunate to experience success as a player and coach, I believe my résumé as a trainer is defined less by what I’ve done as an athlete and more by the work I’ve done as a trainer, teacher, and mentor — helping athletes grow both on and off the field. If you’d like to hear how that approach has impacted players and families, I invite you to visit my Testimonials page.
My Experience & Coaching Credentials
With over 30 years of coaching experience across rec, club, travel, and high school levels, I currently serve as:
Head Varsity Lacrosse Coach at The Ursuline School in New Rochelle, NY — where, over the past eight years, I’ve become the all-time winningest coach in program history. Our team has reached the Sectional Semifinals four out of the last five seasons — including three straight appearances in 2023, 2024, and 2025 — and posted a 36–15 record over the last three years. We’ve produced multiple All-Section players who’ve gone on to play college lacrosse, as well as the school’s first-ever All-American and Academic All-American.
Director of Player Development and coach for R2 Lacrosse, a premier program dedicated to training athletes of all ages and skill levels.
Former Director of Girls Lacrosse at House of Sports, where I turned around a struggling program by building a respected Girls Lacrosse Training Academy that delivered sustained, year-over-year growth and renewed community trust.
Regional coach for the CONNY Region Burn Team at the New Balance All-America Games, and former chair of the Hudson Valley National Team.
Coach with the Yorktown Athletic Club, Croton Youth Lacrosse, Bronxville Youth Lacrosse, and Pelham Youth Lacrosse — helping young athletes build a strong foundation for the game.
I also hold:
NFHS Accredited Interscholastic Coach
NFHS Certified Interscholastic Coach
Certified Positive Coaching Alliance Coach
Certified USA Lacrosse Level 2 Coach
Certified USA Lacrosse Level 2 Instructor
As a two-sport athlete at Yorktown High School, I helped my lacrosse team earn two consecutive State Championship appearances — including Yorktown’s first-ever NYSPHSAA title — before playing Division I lacrosse at nationally ranked Towson University.
I’m also a proud sports parent. Having guided my own children through the demands of youth and collegiate athletics, I understand firsthand what parents look for in a trainer or program: trust, clear communication, meaningful development, and a commitment to their child’s overall well-being. This perspective shapes how I approach every athlete and family I work with.
Most meaningful of all, I’m a proud father. My children have earned numerous honors — from All-Section awards to Big Ten Player of the Week and Inside Lacrosse Division I National Player of the Week — and today, two of them coach at the varsity and collegiate levels, carrying forward our family tradition of giving back to the game.
After decades on the sidelines, my philosophy hasn’t changed: it’s not just about winning, but about building character, confidence, and lasting, lifelong friendships.
For Parents
A Coach Who Understands You Too
As both a coach and a sports parent, I know what matters most: trust, open communication, and a commitment to your child’s overall growth—not just their stats. Here’s what you can expect when your family joins mine.
Over the years, I’ve been on both sides of the sidelines—not only as a coach, but as a dad watching my own children navigate youth, high school, and college athletics. That perspective has shaped how I approach every athlete and every family I work with.
I understand what parents want in a coach or trainer: someone who will help your child develop skills and love for the game, but also keep an eye on the bigger picture—confidence, resilience, sportsmanship, and well-being. I believe in clear communication with parents, honesty about your child’s progress, and building trust so we’re working together as partners.
My mission isn’t just to build better players, but to help every athlete discover what makes them unique, learn lessons that last a lifetime, and create friendships and memories they’ll treasure forever.
Coaching Philosophy
More Than a Game: How I Coach
Coaching isn’t just about drills, the X’s and O’s, or winning records—it’s about building genuine relationships rooted in trust, respect, and accountability, and helping them discover who they are, trust themselves, and grow into resilient, confident people on and off the field.
I believe young athletes grow the most when they’re supported and challenged—pushed to stretch beyond what they think they can do, while always knowing someone believes in them. My goal is to create an environment where athletes don’t just improve their stick skills or game IQ, but also build confidence, mental toughness, and leadership skills that stay with them long after the final whistle.
At every level—from rec leagues to varsity —I coach each athlete as an individual I help them discover their unique strengths, embrace mistakes as part of the process, and understand that stepping outside their comfort zone is where true growth happens.
By focusing on doing the “little things” right, the big things will follow and the score will take care of itself.
