Why students stick with it
It's a puzzle.
Every position is a problem with a few good answers. If you like chess, code, or anything you can get better at by thinking, you'll like this.
It's a real workout you won't have to force.
An hour of games with a partner, and you forget you're exercising.
You'll make friends outside your major.
Students, engineers, parents, and locals train side by side. A coach pairs you up on day one.
The student rate
Join the same day as your free class and your first month is $99. After that, it's $130 a month with a valid student ID. That's two classes a week Monday to Thursday, plus unlimited Friday and Saturday training. Month to month, no long-term contract. It can't be combined with family or commitment discounts.
Beginner classes run Monday to Thursday at 7 PM.
Who you'll learn from
Avery Lorenzato, owner and head coach
Avery started Golden Jiu Jitsu in 2022 to build a gym around how people actually learn. He's a brown belt under Rob Biernacki with nine years on the mats, and he and his coaches read the research on motor learning and turn it into the games you'll play in class.
Nervous before your first class? That's normal. A coach meets you at the door and pairs you with someone who's good with new people.

Questions
I've never done a martial art. Is that a problem?
No. Most people start with zero experience. Classes are built around games, so you're playing from your first class.
Is it just for Mines students?
The student rate is for any college student with a valid student ID.
What if I'm gone for the summer?
Ask us about freezing your membership while you're away.
Is it safe?
Jiu jitsu is a contact sport, and we take that seriously. Coaches manage intensity for new people, and our culture is simple: tap early, play often, no ego.
Try one class. It's free.
Bring a friend from your floor if you want company.
$99 first month applies to new memberships started the same day as your free intro class. Not available to current members. Guarantee requires at least eight classes in your first 30 days of membership (the free intro class doesn't count), with the refund requested within those 30 days; the refund is your first month's payment, and it ends your membership. It covers the first month only: if you paid for a longer term up front, the rest of that payment is not refunded.
