From the reviews

I met Jeff at another gym and started my training because he’s such a kind and trustworthy person. When he decided to start Mythic, it was a no-brainer for many of us to follow him. Jeff and his other coaches are amazing. The new location is plenty spacious, but the family atmosphere is still the same.

Jeff is a Great instructor and one of the most down time earth people. They have GREAT programs, with tons of class options. After taking a break for years Jeff remained patient and supportive and encouraged me to get back on the mats. Definitely recommend this to anyone.

Awesome team at Mythic BJJ..Professor Jeff and the team were so welcoming and knowledgeable..I've done bjj for years but wanted to check out an Eskrema class as my boy and I would love to learn this style. Today was our 1st class and it was great.

★★★★★ — Carlos, Jul 2021

I can confidently say that Mythic BJJ feels like my second home. From day one, everyone has been incredibly welcoming. Professor Jeff’s background in pedagogy really shines through in his teaching style and I’ve learned so much both on and off the mats during my time here.

Your first BJJ class at Mythic 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 when you call. 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.
