USSD 4S Ranch 10750 Thornmint Road, San Diego, CA 92127

"Love it and our kids love it. After trying two other places we finally found a dojo and staff that we love. Kids feel super comfortable and safe here and enjoy going. All the sensei teaching here are awesome!"

"My son has gone here for 2 years and it's such an amazing place. Sensei Stef does an amazing job making the kids feel welcome and successful in their work. All the instructors are wonderful. They also do birthday parties which are SO much fun!"

"Both my children are enrolled here and we couldn't be happier with the top quality of instruction as well as the honest, family-style, inclusive environment that they have created. Your child's well-being and positive development are their top priorities hand in hand with instruction that is both fun and functional. We have seen our daughter thrive in the group classes, and our son receives instruction individualized for his requirements. The extra classes like kickboxing that they provide are a nice option for the whole family too. Highly recommended."

"My son has been going to USSD 4SRANCH for about a year and a half now and he likes it! He is not only learning martial arts but basic values are also reinforced like respect, integrity, responsibility, trustworthiness, etc. The sensei’s are amazing and and work well with the kids. My son has learned so much from them in a short time and the skills and values he learned in karate gave him more confidence that his teachers even noticed it in school. (Minnie)"

"My 12 year old son has been with USSD 4S Ranch for about five years now and I have seen an incredible difference in him. He's growing and maturing with good values that parallel what we teach at home which are supported through this studio. He absolutely loves the program and has been training under Sensei Will and Sensei Stephanie. He's participated in class offerings for weapons training and Ninja nights (before Covid, of course) and loved them all. When I asked him specifically what he loves about the program, he said he likes that he does the techniques on his own (once he's learned it) as opposed to following someone through a routine. He learns not only the routines, but practical knowledge and application as well. I appreciate how flexible they are with rescheduling and how kind and respectful they are to everyone. I am impressed with the older students, such as the brown belts, who have offered a helping hand or a kind word at any opportunity, including young kids! They are definitely doing this program right and I'm happy to be a part of the USSD family."
