We enrolled our daughter in August 2026 and have been very pleased with the structure, discipline and confidence it is already instilling in her. Sensei Nico and his team have created a welcoming and patient environment that meets kids where they are and helps them achieve the high standard they set.

Reviews
My son really enjoys attending this dojo. Sensei, Nico and Sensei Bobby are great instructors. My son has been training for almost a year now, I like the fact that they have two regional tournaments to test the kids skills and knowledge. My son participated this past spring in one of their tournaments and is already signed up for their fall tournament because he loved it so much. This is not a cheap dojo, but I do get the feeling that they do care, love what they do, and want the kids to succeed.
We met Sensei Nico at Red, White and you in 2025. My kiddo had taken karate before at larger environments and wasn't really interested in doing it again but Sensei asked if they liked Pokemon and wanted to learn how to fight like Pokemon. We've been coming here for over a year and it's been great. Sensei Nico really knows how to tap into what individuals are interested in and need to help keep them motivated. We have had a great personlized experience here as a student and as a parent.
