myBJJ Nelson is a Brazilian jiu-jitsu school at L1/76 Vanguard Street in Nelson South, which takes students from age 5 upwards. The school began with Shane Winterton and Rob Tegurtha under the supervision of Stuart Marks from Dunedin, and later grew into its own dedicated training venue in Nelson. Its training is aimed at casual training as well as preparation for international competition, and the school describes itself as a family-friendly, safe training venue.
The school is affiliated with the myBrazilian Jiu Jitsu International Association, founded by Professor Mario Yokoyama, who is based in Sydney and has visited Nelson to teach and supervise the branch. Head instructor Stuart Marks is an IBJJF-certificated instructor and was the first student of Professor Mario to be graded from white belt to black belt. For families in Nelson who want children and adults to train in the same place, the school's age range from five upwards is the main thing to note.
