From the reviews

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.

★★★★★ — C, Dec 2019

Incredible jiu-jitsu school!! Cindy is the best. I trust her so much that I recommended her academy for my mom to train at. The mats are raised and Bert’s soft. Super clean environment. 10/10 recommend!

★★★★★ — Victor, Nov 2022

Visited while on work travel. Cindy is super friendly and welcoming (possibly the friendliest and most observant coach I've seen, apologies to normal coach). The gym is spacious, super clean, and has soft and springy mats! All of the accommodations are available, including showers, changing area, and water fountain.

★★★★★ — Johnny, Nov 2022

Adult class is amazing. Great energy all around. Cindy is a legend and is Amazing with the kids. I honestly don’t know how she does it! She knows every single kids name, even if they are brand new. They respect her and the other coaches and she keeps them in line. Burpees for when they aren’t acting right.

Your first BJJ class at Sleeper Jiu Jitsu

Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

BJJ is a contact sport. Ease in, tap early and often, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
