Smithtown Ninja Academy | Long Island Ninja Classes — Local services in Town of Smithtown

We are a huge fan of Smithtown Ninja!! Highly recommend.

Kathryn (the owner) is amazing. She has created an environment that is supportive & fun (for every level). They have professional coaches & they’re great with the kids.

My kiddo enjoys the weekly classes.

There are Winter, Fall & Spring semesters. (If you want to register after a semester starts - just call, I think you can start up until the 4th week of class).

In the summer they have their weekly classes or a summer camp option.

There’s also the special event “fun run” which is a full course for the kids to go through.

The facility is clean!! They have a nice sized Birthday Party room, too.

Definitely check out Smithtown Ninja - I highly recommend!

Editing to add: My kiddo had his Birthday Party there this year and it was SO much fun!

The instructors were amazing, as usual, and even though we had so many kiddos with different skill levels, they all did great! I brought decorations and they totally set it up while I enjoyed the party and let one parent around the ninja area to take action shots of the kiddos (the other parents could watch or relax in the "parent area"). The party room was super clean and the instructors totally took care of the kids while I ate & enjoyed the party!

Yes, I definitely recommend their birthday...

Had an incredible experience at Smithtown Ninja Academy for our son’s 6th Birthday party. Kathryn and the staff are amazing to work with and the kids all have the best time! Reserving and scheduling the party was so easy and Kathryn communicated with us the entire time to make sure everything went smoothly. The day of the party, they took care of everything, were so patient with the kids, and made sure they all had fun and were safe. The other parents could not stop talking about how cool it was!

The gym itself is so impressive and everything is brand new and clean. We will definitely be back with our son and I may even look into trying it out myself!

100% recommend this place to everyone....

I had my son’s 7th birthday party just today and had to get on to write this review immediately! Smithtown Ninja is the place to be. From the moment we arrived until we left, Kathryn and her staff took care of EVERYTHING. They were so great with the kids and had smiles on their faces the whole time. You can tell they all genuinely love what they are doing. My son and his friends didn’t want to leave. This place is so cool- even the parents wanted in on the action! If you are looking for a place that is different from all of the other birthday party spots, look no further!! You will not be disappointed! Thank you Kathryn and the Smithtown Ninja Staff for making my son’s birthday one we will...
