"Our son has been going here for 3 years now, and Sensei Perez has been amazing. Every class he teaches, he's there 100% for the kids. He's a great mentor and role model, a staple in the Medfield community."

Medfield, MA · In Family We Trust
Strength.Focus.Confidence.
Taught by Sensei Rolando Perez — 50+ years on the mat, still on the floor teaching every week. Since 2011 we have taught Medfield kids how to stand tall, focus, and avoid a fight rather than pick one.

01 / Why Medfield families choose Perez Martial Arts
More Than Kicks.

Not Your Typical
Martial Arts School.
01
You Meet Sensei First
Before anyone signs up, Sensei Perez sits down one on one with you and your child to talk goals — focus, confidence, self-control — and builds from there.
"We met one on one with the lead instructor where he took time to talk with both my children and me." — Heather K.
02
Unlimited Classes
Lots of class times through the week, and members can come as often as they like. Busy family schedule? There's a slot that fits.
"The UNLIMITED classes my children can take in a month." — Heather K.
03
A Life Lesson Every Month
Each month has a character theme, taught through Sensei's stories, with take-home "homework" so parents can keep the conversation going.
"I love the stories that Sensei tells to give us examples of what we're learning that month." — a 7-year-old student
04
Fun Fridays
Friday classes are the one kids beg for. Games, challenges and high energy, with the skills still sneaking in.
"He loves learning all the forms, kicks and punches and Fun Fridays." — Andrea M.
05
Silly, Then Serious
Sensei Perez gets the whole room laughing, then gets it focused. Kids work hard because they're having fun, not because they're scared.
"He is silly sometimes but serious when we need to learn." — a 7-year-old student
06
Older Kids Lead Younger Kids
Teens in the Leadership Program help run the little ones' classes. Younger students get role models; older ones learn to lead.
"The older students helping the younger kids is great." — Christina J.
07
Patience For Every Kind Of Kid
High-energy, easily distracted, shy, or learning differently — staff give enough one-on-one attention that every child finishes class with a win.
"He is young, high energy, and extremely distractable. The staff give him enough one-on-one attention that he can complete each class successfully." — Lindsay A.
08
The Whole Family Trains
Parents, kids, even grandparents take class here. One dad earned his black belt alongside his sons. Some families have been with us for ten years.
"My grandson started last year and I started this past November. You're never too young or too old!" — Marie B.

04 / Your Head Instructor
Sensei Rolando
Perez.
Sensei Rolando Perez started training at 12 years old and has never stopped — more than 50 years on the mat. He opened Perez Martial Arts in Medfield in 2011 and still teaches classes himself, with a specialty in ages 4 to 10. He built the academy around one idea: martial arts should teach a child to avoid a fight, not pick one.
