Lineage: Mitsuyo Maeda > Carlos Gracie > Carlson Gracie Sr >
Carlson Gracie Jr > Alan Stockman
Alan began training Brazilian Jiu-Jitsu under Luiz Filho in Fortaleza, Brazil, in October of 1997. He lived, trained and competed in Brazil for almost four years. He earned 2 degrees on his Blue Belt before returning home to the United States. Stockman continued training after returning back to the US. At the time, there was not much Brazilian Jiu Jitsu in Northern Indiana, so he traveled often to work with other Black Belts all over the US. He continued until he earned his Black Belt in 2011 and at the same time opened up his school in Greenwood, Indiana.
Before Brazilian Jiu-Jitsu he did a little Tae Kwon Do as a teen, but it never really captured his attention. It wasn’t until he was living in Brazil and was invited by a friend to attend a class. After the class he was paired up with a young kid that was maybe 15 years old. Stockman was 24 at the time, bigger, stronger, but found that his physical advantage didn’t help while live training. He was fascinated at how the technique was so advantageous. That day he bought a gi and never stopped training.
Before Brazilian Jiu-Jitsu, he had competed in soccer and cycling extensively. It was through soccer, that he found his path to go to Brazil. Nowadays if he is not in the gym, he likes to fish, hunt, read, and play chess.
