O'Sensei Febres did his Oriental Medicine internship at the Conmaul Oriental Medicine Hospital in Seoul, Korea.
O'Sensei Febres began his career in the martial arts at the age of twelve. He studied Okinawa Te, as well as Yoshu Kai and Yoshu Ryu under Sensei Bill Solano, Okinawa Kempo under Sensei Carlos Montalvo and Okinawa Kobudo under Kimo Wall as well as Sanuces Ryu Jujutsu under Profesor Moses Powell and USA Guju Ryu under direct tutelage by Grand Master Peter Urban. In 1987 he attended the second World Ninja Summit in Ohio where he trained with masters such as Tetsuya Higuchi and Shoto Tanemura. At that time he joined the Bujinkan Fellowship International, and was awarded Study Group Status for his Dojos in Puerto Rico.
In 1988, he attended the third Annual World Ninja Summit, where he performed an official demonstration of the techniques of Nindo Ryu. He continued his study of Togakure Ryu Ninjutsu (as it was called at that time), and moved to the United States in September of that year. He established the first Nindo Ryu Dojo in the continental US in November 1988. At that time he was comparing and exchanging information in his system with Sensei Hector Rodriguez (Circle of the Samurai Ninpo Jutsu) in New York. Later that year, he receives a Shodan from Sensei Hector Rodriguez in Ninpo Jutsu (Koga Ryu lineage).
In the spring of 1989, O'Sensei Febres traveled to Ohio to continue training with Higuchi in Togakure Ryu as well as Higuchi's other arts: Iaido/Iaijutsu, Kenjutsu/Kendo, and Taiho Jutsu. He also attended the fourth Annual World Ninja Summit in July of that year, in witch he was invited to participate as a member of the staff at the event. At that time he was offered the chance to test for rank in Togakure Ryu, but declined the opportunity. He maintained communication with Higuchi Sensei, but for all practical purposes, he focused on perpetuating Nindo Ryu. He established the second US Nindo Ryu Dojo that same year.
