My 9yr daughter said Cindy is the best coach ever and she would stay there in her Ju-Jit-su life.

1st point to make - you get what you pay for. Think longevity. sure, I paid 99$ to start got my Gi for $150 and paid $120 a moth their after. I also was in a gym that was not making me feel welcomed, they did not foster a sense of family I (and most) need to succeed. I also noticed these gyms have a "BRO" mentality filled mostly with men. I am a female in my mid 40's. I do not thrive in those types of gyms or an environment that fosters a high school mentality, or clicks! Not all, but many of these "lower cost" BJJ gyms are just like this, and if that is your style, maybe this gym is not for you

We have been training under Cindy for the past 10 years. It started with my kids training with her and I soon after jumped on the train. Cindy has a magic touch with kids, meeting them where they are at and bringing their individual strengths out of them. My kids are not only becoming skilled martial artists because of her instruction but they are also respectful, they demonstrate good sportsmanship and are now entering leadership roles by helping Cindy with coaching smaller children. As if that wasn't enough, Cindy has created a wonderful atmosphere for entire families to train. Her gym is a safe

Absolutely beautiful gym - I had a wonderful time dropping in at Sleeper. Professor Cindy is energetic and knowledgeable, and provides meaningful instruction in a super unintimidating way, especially for new students! Speaking of which, Cindy's students have truly internalized her attitude and talents - they were friendly and skilled training partners.
I have nothing but praise for Sleeper Jiu Jitsu! Thanks so much Professor!
A note for anyone reading this, the front door of sleeper is a smidge hard to find, you have to go up the stairs (inside) and to the second story! She has a video online

We have been training with Prof Cindy for 6 years and we have only had positive experience. Her talent in jiujitsu and in teaching is top notch but what makes her special is her willingness to connect with her students and their families to build a community that not only cares about learning jiujitsu (because you can get that in many places) but deeply cares for each others’ well being. We highly recommend everyone to check this place out.

Sleeper Jiu Jitsu is an amazing place. The school and atmosphere of the school are second to none, Cindy is an even better Professor and the overall vibe has been a great experience. The gym is immaculate and has every amenity you would need.
I actually followed Professor Cindy from a prior school in order to learn from her and her vast knowledge of the sport. I can not recommend coming here enough, everyone is friendly, it is truly a great place to train and learn and it has the feel of a family experience, not just another gym.

Sleeper jiujitsu is a terrific place to train for yourself, or any person in the family. Cindy Hales is a stupendous instructor whom is highly skilled and extremely patient! Her jiujitsu is crazy good followed by No-gi grappling. Cindy, herself is genuine, humble, and passionate. Cindy is an instructor who cares about each of her students and her students progression. She will help you reach your goal whether the intention is to strive to compete in a local competition or just get in shape and learn self defense . She loves her students and her students lover her.
Cindy is always ensuring that

Cindy does a great job to build a strong team and a welcoming environment in her gym. Her ability to teach moves to people who are new to jiu jitsu is remarkable.
I started my jiu jitsu journey with her and I can safely say that you will not find a safer and more welcoming environment to train and grow.
I highly recommend you to check this gym out if you are in the area.

I have been training brazilian jiu jitsu under Cindy for 2+ years. She has a special gift for breaking down techniques for people of all ages, sizes and abilities. She structures the curriculum in a way that allows us to develop our skills from week to week.

Cindy has created an incredible atmosphere in which to learn, get a great workout and to be part of a fantastic community. I wouldn't train anywhere else.

Cindy Hales makes everyone feel welcome and valued. When you’re tying something new, learning or just want a great workout. It means a lot that the environment is warm and open. Let alone Cindy did a magnificent job with the gym, it really is the best place to begin, practice and fine tune your skills.
