"I have been training at Dedeco for a year and a half. It is an amazing experience. The instructors are great. I am really impressed by the culture. The higher belts really take time to mentor the new students. I would highly recommend."
"I am visiting Cape Cod from NJ and was looking to drop into their 9:00am no gi class only to show up to a closed gym. I showed up 30 minutes early and waited around. Nothing on their social media or website said anything about being closed. I drove for over an hour to get here."
"They offer so many classes that work with many different work schedules. The people here are like family. Everyone is kind and considerate. There is no other school I would want to train at."
"I've been training under Dedeco for almost 11 1/2 years now, and although I've never been to another school, I can tell you that it's the best on the South Shore. The community is great, and the comradery even better. Everyone, instructors and students alike, lift you up and help you on your journey, regardless of age, experience, or belt. Best place on the South Shore to train."
