The small seed that began to grow in Asunción is today flourishing in many countries, including the United States, where some of the most successful schools are run by instructors formed in the STF.

One of his current projects for the STF is to make each country independent with its own legal structures and a senior instructors’ council to help each country’s members, new instructors and school owners in order to develop martial arts leaders and entrepreneurs.

For Chief Master Ozuna, being a leader in one of the biggest martial arts organizations in the world and influencing positively in so many people’s lives is a blessing and an honor, in addition to the great responsibility of doing the right thing.

"When one leads a group of people like the STF, there is no room for failure. If you fall down, you have to get up fast. Everyone has very high expectations and you have to respond with actions, as well as positive attitude and results. I am motivated by challenges, and making STF work in countries like ours, using a first world business structure, is truly a challenge."

"STF gives me the blessing of having wonderful Instructors and students in many different countries in South America and to live doing what I like most: Songahm."
