What People Are Saying

  • Very clean, spacious, and a great selection of gear to use.

    Joshua C.

  • I started out doing adult martial arts, but liked the school and the style so much I have now also taken up Muay Thai. Both classes are a lot of fun. I am learning something new every time, and I’ve become much stronger (no more back pain, hurray!). For the quality of instruction, number of opportunities to train throughout the week and individual attention you get it’s really very good value for money. I cannot recommend this place enough!

    Lauren D.

  • This is a great place to learn karate for children the instructors have a lot a patience and they are also very professional and still make It fun for kids.

    Ana Maria L.

  • This is an awesome martial arts studio. The owner runs a clean operation, and the instruction is top notch. The dojo is well appointed with safety padding on floors and pillars, and has floor to ceiling mirrors to check your form during classes. I hope all aspiring martial arts students and aficionados alike take note of this hidden gem!

  • Was extremely impressed with how clean the dojo was! The Judo Instructor Sensei Mo was very friendly welcoming and knowledgeable. Cant wait to go back.

    Tony D.

  • I've been going here for almost a whole year, and I absolutely love the place. It's welcoming, fun, clean, and a great workout! The instructors are friendly and kind, they offer a lot of different classes, and it's great for both kids and adults. To me, it's a perfect middle ground between the extremes of super hardcore bro gyms that focus only on competition, and flakey programs that give you exercise but no real martial arts training.

  • This is a great addition to Medford. The studio is clean and the instructors are phenomenal. There's a great sense of community and the atmosphere is welcoming for anyone who is new or has experience in martial arts, kickboxing, or mauy thai. Since joining the studio, I have been recommending it to my friends since I'm always learning so much here and growing my skills in martial arts.em

    Kristina B.

  • As a new student to martial arts I really appreciate their attention to detail, stories about their previous experiences and of course getting in a good workout! I have had nothing but a great experience and look forward to many more classes. If you are considering starting martial arts or just want a good workout in a positive setting, I highly recommend Sigma.
