"We absolutely love Hassett’s! This is our first jiujitsu experience and my kids (12 & 8 years old) have been going here for over a year. JP and the entire staff there are amazing with kids. They are kind and encouraging but also teach them to be disciplined in their behavior and practice. My kids enjoy BJJ there and look forward to it and have definitely grown more confident. I love what they teach them and that they will carry their self defense skills through the rest of their lives."
"Get yourself and your kids off the couch. Get in shape and learn the best martial art for self defense. Myself my son and daughter train here, couldn't ask for a better environment for them to learn, grow and have FUN!"
"The professors are amazing extremely good with everyone. Teaching the importance of self awareness, respect,and self defence. Great people, and atmosphere, a great place to send your kid to learn, and grow."
"Update: 3.5 years later, both of my children and my husband train here now and they love it. It's become like a little family for them. Hoping to join when my schedule gets less hectic. Still 5 stars all the way Original: my son has been coming here a little over two months now, and I couldn't be happier. I was a little nervous starting him in Jiu Jitsu knowing very little, but I was able to actually have a phone conversation first with the manager. My son loves it here. All of the instructors are amazing and work so well with the children. They make it fun, but also very useful."
