LittleNinjas.
A preschool class designed with childhood-development experts — not a watered-down karate class. Threes and fours learn to listen the first time, wait their turn, and do things for themselves.

Sound familiar?
You Are Not Looking For A Tiny Athlete.
- You ask three times before anything happens.
- Big feelings turn into big meltdowns.
- They freeze when other kids are around.
- Nothing holds their attention for five minutes.
Three and four year olds do not need a black belt. Here is what they get instead:
- They respond the first time, because that is the rule on the mat.
- They learn to name it, breathe, and try again.
- They walk in, find their spot, and say their own name out loud.
- They hold focus through a whole drill — and want another.

Designed For This Age
An age-specific curriculum for the preschool brain
Little Ninjas is built around four areas of development at once: physical development, emotional growth, cognitive skills, and socialization. Every game has a purpose behind it. Balance drills build the core they will sit up straight with in kindergarten. Turn-taking builds patience. Following a three-step instruction builds working memory. It looks like play from the parent bench, and that is exactly the point — three and four year olds learn through play or they do not learn at all.
Listening The First Time
Following directions is a skill we drill on purpose, class after class.
Motor Skills & Coordination
Balance, jumping, kicking, catching — the gross-motor foundation for every sport they try later.
Emotional Control
How to lose a game, wait a turn, and try something hard without falling apart.
Socialization
Sharing space with other kids, taking turns, and cheering for someone else.
Independence
Tying their own belt, lining up on their own, bowing in without a parent hovering.
Real Self-Esteem
Confidence they earned from doing something hard, not from being told they are great.
Short, Structured, Never Boring.
Bow In & Warm Up
Shoes off, line up on their own spot, and a warm-up that burns off the car ride.
Skill Of The Week
One skill only — a kick, a block, a stance — broken into pieces a four year old can hold.
Development Game
The block we are working on that month, hidden inside a game they beg to repeat.
Mat Chat
A one-word life skill they can repeat to you in the car: patience, respect, focus.
Bow Out & Stamps
Effort recognized out loud, then they walk out taller than they walked in.
30 min
Class length
Parents are welcome to stay and watch every class. Most do.
The first month
What You Will Notice First.
Parents tell us the same three things after about four weeks.
They listen the first time more often — at home too.
They can hold still and pay attention for longer stretches.
They talk about class all week and practice in the kitchen.
They walk into new rooms without hiding behind your leg.
For nervous parents
Nobody Gets Hit In This Class.
Little Ninjas is non-contact. There is no sparring, no partner striking, and no pressure.
Non-Contact By Design
Kicks and strikes go into padded targets held by an instructor. Never into another child.
Coached, Never Yelled At
Age-appropriate voices and expectations. A three year old having an off day is normal, not a problem.
Small Groups, Eyes On Everyone
Class sizes stay small enough that every child gets corrected, encouraged, and seen.
Every Class Ends With A Win
Three year olds do not remember drills. They remember how class made them feel. Every Little Ninjas class is built so they walk out taller than they walked in.
Celebrated For Listening
We cheer the first-time listen as loudly as the best kick, so the habit sticks.
A Teacher Who Gets Down On Their Level
Sensei Perez has specialized in young kids for decades. Shy kids warm up fast.
Pride They Bring Home
Expect bows at the dinner table and demonstrations for grandma.
Why Families Stay
Families come for a trial month. They stay because Sensei Perez is still the one on the floor.

"My twin 4-year-olds have been at Perez Martial Arts for a month. Mr. Perez and his instructors are amazing at keeping the Little Ninjas classes fun and engaging. Highly recommend!"
— Marykate Hunt
"We met one on one with the lead instructor, and he took time to talk with both my children and me. Longer attention spans, less impulsivity and confidence were high on our list. Our search ended here."
