BJJ in Somerville

Somerville's three listings span GFTeam-affiliated competition BJJ, Boston's flagship Muay Thai gym, and an independent. The standout is **Brazilian Martial Arts Center (BMAC)**, a 7,000+ sq ft GFTeam-affiliated academy founded in 2001 by **Marcelo Siqueira** — a 5th-degree BJJ black belt under Julio Cesar Pereira (GFTeam founder), 1994 World Champion, 6x Parana State Champion, ex-Chute Boxe Academy under Master Rudimar Fedrigo, plus a 4th-Dan Wado Ryu Karate black belt and Black Belt Judo. Siqueira is also a North American Olympic Committee member. The instructor bench includes **Alex Marshall** (BJJ black belt under Siqueira, brown belt Judo, IBJJF & Grappling Industries certified referee). **Sityodtong Muay Thai Academy** at 100 Broadway is Boston's premier Muay Thai academy, founded in 1996 by **Kru Mark DellaGrotte** under Master Yodtong Senanan (Pattaya City, Thailand) — Sityodtong has trained many UFC fighters and is the lineage source for several Boston-area coaches' Muay Thai credentials, though BJJ is not a stated program at this location. **617 Brazilian Jiu Jitsu** rounds out the trio, but its website returned no extractable content during the last crawl, so program, instructor, and pricing details are unavailable.
