Meet Coach Lou
Hi, I'm Louis Barreto Nieves, founder of Lou's Lax Lab.
As both an educator and coach, I've dedicated my career to helping young people grow through learning.
My coaching philosophy is simple:
Every athlete deserves individualized instruction, positive encouragement, and a training environment where they can build confidence while developing the skills to compete at their highest level.
Whether you're picking up a stick for the first time or preparing for varsity, club, or collegiate competition, my goal is to help every player leave each session better than they arrived.
Personalized Training: Built for Your Game
At Lou’s Lax Lab, we don’t believe in one-size-fits-all coaching. Every player has a different set of goals, a different position, and a different learning style. As a college player and a professional educator, I specialize in identifying a player's "missing link" and building a custom lesson plan to fix it.
Choose Your Focus
Your session is 100% customizable. We can spend the entire time deep-diving into one specific skill, or rotate through a comprehensive "Total Player" workout.
The Sniper (Shooting & Offense): We break down mechanics—from time-and-room power to deceptive shooting on the run and finishing inside.
The Lockdown (Defense): Focus on footwork, approach angles, body positioning, and effective stick checks that don't take you out of the play.
The Foundation (Stick Work & IQ): Master the essentials of cradling under pressure, passing with both hands, and understanding the "why" behind every move on the field.
The Specialist (Goalie Work): Building a solid arc, explosive reaction time, and the "coach-on-the-field" communication skills needed to lead a defense.
The Athlete (Speed & Agility): Lacrosse is a game of inches. We incorporate explosive movement and footwork drills into every session to ensure you’re the fastest player to every 50/50 ball.

Our most popular session. The extra 30 minutes allows us to bridge the gap between skill work and game-speed execution. We don’t just work on the "how"; we work on the "when" and "why." This session allows enough time to work on stick skills, positional defense or offense, and the explosive footwork needed to win 50/50 balls.
Focus: Skill mastery + Lacrosse IQ + Athletic conditioning.
Goal: Build a well-rounded athlete who understands the flow of the game.
Investment: $110 Best Value | Best For: Highly motivated players, college prospects, or athletes working on multiple positions (e.g., a two-way midfielder or a goalie who also plays field).
The two-hour "Masterclass" is a deep dive into every aspect of the game. We have the time to break down complex movements, work on various shooting angles, and run through high-repetition defensive sets. This session simulates the physical and mental demands of a full game, ensuring the player is prepared for the highest level of competition.
Focus: Total immersion. Positional deep-dives, endurance, and advanced Lacrosse IQ.
Goal: A comprehensive transformation of the player’s technical and mental game.

Our
brand vision
At Lou’s Lax Lab, our vision is to redefine athletic development by treating the lacrosse field as an extension of the classroom. We believe that becoming an elite player requires more than just physical repetition; it requires a deep understanding of the "why" behind every movement. Our goal is to empower the next generation of lacrosse players—from youth athletes just picking up a stick to high school and collegiate players looking to sharpen their competitive edge. By combining the structured approach of a professional educator with the experience of a collegiate athlete, we strive to build players who are not only physically dominant but are also the smartest students of the game on the field. We are committed to providing athletes of all ages and skill levels with the specific tools, mental framework, and personalized drills necessary to take ownership of their own growth and reach their highest potential in the sport.
