Owner and Head Coach
John Spezzano has been a student of martial arts for the last 35 years and a student of strength for over a decade. Covering as many combat bases as possible, John has instructor certificates in Filipino Martial Arts, Pencak Silat and Jeet Kune Do from Guro Dan Inosanto, Muay Thai from Ajarn Chai Sirisute, Wing Chun from Sifu Francis Fong, a Silver Glove in Boxe Francaise Savate from Professor Nicolas Saignac and a Brown Belt in Brazilian Jiu Jitsu from Professor Shawn Williams.
From 1995-2009 John was a staff instructor at the Inosanto Academy of Martial Arts, in Los Angeles, teaching classes in Filipino Martial Arts, Pencak Silat, Boxe Francaise Savate, Jeet Kune Do and Muay Thai. In 2010 John stopped teaching at the Inosanto Academy and started the Muay Thai program at Five Star Martial Arts in Los Angeles where he taught until the end of 2016.
John trained with Dr. Mark Cheng for 2 years prior to completing his RKC level 1 kettlebell certification in 2008. In 2010 Black Belt Magazine published John’s book “The Martial Arts / Kettlebell Connection,” one of the first books available to help martial artists improve their combat sport performance through the use of the kettlebell. John completed his level 2 RKC in 2012, (Pavel’s final level 2 for Dragon Door). Shortly thereafter, StrongFirst was created and John moved to the new company, maintaining his affiliation with Pavel. John re-certified as a Level 2 SFG in 2014 and was promoted to StrongFirst Team Leader in 2016 and now trains and helps certify future generations of StrongFirst kettlebell instructors.
In addition to overseeing the programming and curricula for Source 1 Martial Arts and Fitness, John also teaches workshops around the country and throughout Europe for martial artists who want to get stronger and move better.
