In 1997, Professor Zakk started his martial arts journey at the young age of 5 years old. After several years of training in Tang Soo Do, an accident forced him to take a long hiatus. Later in 2009, Zakk was introduced to Jiu-Jitsu and Muay Thai, becoming instantly obsessed and relentlessly spending the next 3 years training.

In 2012, he then made the decision to cease his MMA style training, and fully devote his training time to the grappling arts of Jiu-Jitsu, Judo, Wrestling, and Sambo after falling in love with the constant mental and physical challenges they required.

In 2013, at the age of 20, Zakk felt the need to seek out more challenges and enlisted in the United States Marine Corps. After returning home from his initial training, Zakk would spend the next several years fine-tuning his skills as a Jiu-Jitsu student, coach, and competitor until receiving his Jiu-Jitsu Black Belt in July of 2019.
