What People Are Saying

“Sampai Sarah is the best! Not only does she know her stuff, she is kind, loving, and challenging. She truly enjoys teaching her students and encourages them to go beyond what they think that they can do. The students learn kata, kumite, discipline, manners and more! Each class ends with a fun game.”

— Lesley S

- Carina L

“We love the karate class with Pintsize! It was great to keep my 5-year-old son stay active at home during the pandemic. The sensei keeps kids engaged with different games, exercises, and of course, karate moves.”

- An-min Wu

“My kids loved this class with Ms. Sarah. She was very patient and kind with my kids but also had the right amount of discipline. My daughter was very timid starting and then became comfortable quick because she gave my daughter her space until she was ready but kept including her until she felt comfortable. Both of my kids knew nothing when they started and now they are way more knowledgeable. Her prices are very reasonable considering all the competition out there and more one on one attention versus the other classes that have way to many kids with only one instructor. I would highly recommend this class.”

— Caroline G

“My son thoroughly enjoyed it. He said it was 'The Best!'. He learned some cool ninja moves, and I loved the fact that they talked about taking responsibility.”
