Fernando walked in tonight, started looking around and said, “look at all the guys from the first school still on the mat!”

All these guys trained at the first location (the old yellow exchange hall in South Acton) which we left about 20 years ago)

It’s great to have so many of us still training from the beginning of Mass BJJ. A little more grey, but still on the mat!

Congrats to Gordon on earning his Purple belt!

I know that people generally don’t like having their age posted on here but… I’m just going to say Gordon, who looks like he is in his 40’s is over 60 years old. It’s not unusual for him to double up the 6:00 and then the 7:00pm classes. I’ve been watching his rolls with kids 20-40 years younger than him. The round ends, he gets up a little slower than them but he gets up, fixes his belt and gets back in line for the next round.

It is inspiring to see someone just show up, put the work in and keep going, no excuses.

Off the mat, Gordon is an incredibly kind and generous person. He has reached out to offer help to so many people in our community.

Congrats on the belt! Keep on grinding!

Congrats to “Big Nate” on earning his blue belt! Even though his usual joking response to having a technical problem is “I should probably get bigger…”

Excluding his first day on the mat, when his only frame of reference to grappling was having seen Quinten Rampage Jackson get out of a triangle choke.)
For a 300+lb powerlifter, I never worry about how he rolls with people, he’s a gentle giant on the mat and always joking around and having fun.

Congrats Nate! Now go eat Tokyo!
