★★★★★Christina Calvao-MedeirosWe love this coding class! As a busy mom, I was looking for something that would genuinely engage my kids — and the instructors here totally deliver. They have a real gift for making coding fun and approachable, and my boys actually look forward to going every week. You can tell the teachers are passionate about what they do and know how to connect with kids at their level. Highly recommend to any parent looking for a quality, enriching activity.
★★★★★vinod mohanMy son loves this class. We did try some other coding classes but never clicked. Now he learns the coding from basics, not rushed. He now knows the prospects of learning coding and enjoys it.
★★★★★sundaresh R.IyerMy 9 year old attended the Minecraft camp at Firefly Coders and really enjoyed it. They were super friendly and supportive, and he learned some programming basics in a fun way. Great experience overall!
★★★★★Amr AbdelhafezFirefly coders is the right place for kids to grow their math and coding skills in supportive environment. The instructors are highly skilled and care about each kid in the group unlike other competitors. I would recommend Firefly coders to all kids who want to build a strong foundation in math and coding.
★★★★★Brittany FreitasMy son has been attending Firefly Coders math tutoring for about a year, and we couldn’t be happier with the experience. He genuinely looks forward to his weekly sessions with Tyler or Abishek (Abi). They make him feel comfortable, and their patience and understanding have helped him build confidence in his math skills. We’re very pleased with the progress he’s made and look forward to continuing to work with this wonderful team!
