Powered by GoogleMy son with zero coding experience had his 8th birthday here and it was the absolute best! With. Mix of kids aged 4-8 everyone had a wonderful time. The teachers did a great job teaching the kids about Minecraft and coding and the parents were amazed how chill the event was! Joanna and her staff are very kind and helpful for every step of the bday - highly recommend! We will be enrolling in the program next.
Impeccably clean, well organized program with professional staff and curriculum. My son made significant progress. We shared this program with many friends and some signed up and are happy as well! Highly recommend.
My son loves going to CODE Ninjas Waltham, His interest in coding got an immense boost. It's a great way to keep them engaged at the center and also at home as they can keep practicing. The co- ordinator and the faculty member are very good, and professional. They are always flexible with time and class schedule. I would highly recommend it for kids interested in coding.
So happy we signed my son (age 7) up for Code Ninjas! He started a few weeks ago and is super eager to learn. The owner, Joanna, has been incredibly helpful and welcoming since I first called to inquire about the program. The senseis (instructors) have also been great with my son and he looks forward to his sessions with them. As a busy, working parent trying to balance 2 kids' activities, I really appreciate the flexibility of the drop-in schedules that Code Ninjas offers. Can't say enough good things about our experience thus far!
I can't praise owner Joanna Chua highly enough! My two boys (ages 5.5 & 7) have been eager to 'make robots' but each class I've signed them up to has been a flop. Either they spend too much time glued to a screen or they get bored by the projects that are uninteresting. Joanna asked me for the background on what they'd done and wanted to know what they were interested in and then she crafted a perfect week for them when we were in from out of town and other kids were in school. They absolutely loved it and came out so excited with their robots and work they'd done. I highly recommend her and Code Ninjas and we'll definitely be back! It also gave me the great idea of giving friends and family in the area gift certificates for her classes. You can't go wrong with that as a gift!
