Be Honest

Nobody Wants To Host It At Home.

  • Twelve kids loose in your living room

    Twelve kids on a mat, following an instructor

  • You running games you invented last night

    A ninety-minute plan that has run hundreds of times

  • Cleaning up frosting until 10pm

    You walk out when the party ends

  • Two kids sitting out, bored

    Every guest active the whole time

90–120

Minutes, fully run by us

Designed For This Age

Structure is the reason it works.

These parties are run by the same instructors who teach our kids classes every week, in a school that has been family-owned in Newtonville since 1999. They know how to hold the attention of fifteen excited children, how to keep the room safe, and how to make the birthday child the center of it without embarrassing them. You bring the cake and the guests; we bring the plan.

Board Breaking For Everyone

Every guest breaks a board and takes the halves home.

The Birthday Kid Leads

They get to run part of the class in front of their friends.

Safe And Supervised

Padded floors, black-belt instructors, clear rules from minute one.

Up To 30 Guests

15 included, then $15 per extra child up to a maximum of 30.

90 To 120 Minutes

Long enough to be a real party, short enough to end well.

Zero Cleanup

We set up and we clean up. You leave with the photos.

Within The First Few Weeks

What Parents Love

You came to celebrate your kid, not to run a party. So you won't.

You actually watch the party instead of managing it

Every guest is busy, so nobody melts down

Fifteen kids listening to one instructor. Really.

It ends on time, and you walk out with no cleanup

The Moment That Changes Everything

The Moment They Remember

Your child leads their friends through real karate, then breaks a board in front of everyone.

Center Of Attention

The birthday child goes first, helps lead class, and gets the loudest cheer.

A Real Accomplishment

Every guest breaks a board and takes the halves home.

Photos Worth Keeping
