In early November, my son’s team successfully competed in the FLL Qualifiers. In addition to qualifying for Regionals, they also won “Best Robot Design” award. Credit for the success goes to the team & their coaches. Sensei David & Sensei Vijay were supportive of the team throughout the process, giving the team the guidance & knowledge that set them up for success. The team did encounter challenges along the way & each of those were handled well. My son learnt a lot through this experience. And it’s not just about robotics & coding but also about teamwork & creative solutions to challenges. A huge shoutout to Sensei Vijay & Sensei David for getting the team ready for the competition. My son is excited he will be continuing at Code Ninjas for the Regionals prep.

My son has been going to Code Ninja for the last 2 years now (Create program, FLL and FTC coaching) and I am impressed with the quality of education and the dedication of all the Sensei in the center. Special call out to Sensei Vijay, Sensei David and Sensei Neiyo for their guidance and support to my son’s FLL team (Brain Bot) which helped them in getting 2 awards during the recent FLL NorCal competition. I have seen my son learning not just coding, but also teamwork, presentation style and be a creative thinker. Thank you Sensei Vijay, Sensei David and Sensei Neiyo.

I discovered Code Ninjas in the summer while searching for an engaging activity for my son. He’s an avid fan of Roblox and Minecraft, and Code Ninjas offers a variety of summer camps and weekly classes specifically designed for kids. One of their standout offerings is the Lego Championships like FLL and FTC, where Coach Vijay demonstrates exceptional expertise. He understands the unique needs of each team and possesses the ability to motivate and guide them effectively. Our team’s remarkable success in the First Lego League (FLL) can be attributed to the unwavering dedication of Coach Vijay, along with his fellow Senseis David and Neiyo. I am truly impressed by Coach Vijay’s commitment to the team’s success. He goes above and beyond to provide the necessary support and guidance, ensuring that our team achieves its full potential.

Code Ninjas is an amazing place for kids to learn valuable coding skills in a fun and engaging environment. My child absolutely loves going, and I've seen a significant improvement in their problem-solving abilities and creativity. The instructors are knowledgeable and supportive, making learning enjoyable. Highly recommend for any young aspiring coders!

★★★★★The Thinker's Bible

Code Ninjas is fantastic. My son loves it. They are expert, patient and thorough. Great teachers and coaches. They focus on students doing their own projects for competitions instead of the coaches doing the work for them. My son's Code Ninjas team won the Innovation Award at a regional competition, the first time a rookie team had won that award. Once I paid for different workshops at another such school to compare - that school cost 2x as much and my son learned 1/2 as much, if that. So I took him back to Code Ninjas and the result was an Innovation Award for the regional competition.
