My son and I are training here together and both love it. Great academy with a family feel!
Sampa is big enough to keep u learning and changing but small enough to be friendly, inviting and oh so challenging. If you want to work out and never be bored, u got to join a bootcamp session. It is awesome. Julie is the best! Always on point! She knows her stuff and is always willing to help you be a better you. Very cool gym!

Sampa is a top tier BJJ academy. The inside is huge with plenty of room, the staff is always friendly and informative, the students have a reciprocating desire to learn and get better, and the instructors are passionate and patient to teach and excited to see you succeed. Professor Nathan Basseto is incredible and I highly recommend him
If you are looking for a BJJ academy that stays true to the art of BJJ, this place is it. Sampa is owned by a globally recognized 4th degree black belt named Professor Renato Migliaccio. Prof. Renato strives to provide high quality BJJ classes and it shows through his continued practice to maintain training in BJJ and other mixed martial arts. Prof. Renato has the ability to recognize the interests and athletic needs of the community he serves. I highly recommend this academy for children as young as 3 up to adults. If you come to Sampa you will be warmly welcomed to the Sampa family.
What not to love this place?? My son has been with Sampa for 2 years and he loves this place so much that he literately goes there 7 days a week! Great coaches and staff! They genuinely care about their students.
Hands down the best choice I ever made for my son. He’s learned discipline, has more confidence, and can defend himself.
Clean facility, amazing staff, and Prof. Renato is very involved with his students.

Why Youth Jiu Jitsu Medals Do Not Guarantee Adult Success Watching your child win a jiu-jitsu tournament is a proud moment.

Why Injuries Don’t End Martial Arts Journeys One of the most rewarding parts of being a martial arts coach is watching students transform over time. While people often focus on belts, medals, and competition results, the most meaningful improvements usually happen where nobody can see them. Confidence. Discipline. Resilience. Character. Over the years, I have […]

At Sampa Jiu Jitsu Martial Arts, we strongly believe that martial arts are about much more than medals, rankings, or social media pictures.

This weekend was another perfect example of that philosophy […]
