DLab Lynbrook New York- Lead Instructor – John Leabo


John Leabo has over 19 years of conituous study of Martial Arts. He began studying Martial Arts in New York City in 1996 and his major focus has always been on Martial Arts that are both practical and effective for self defence. He began teaching Martial Arts in 2008 as one of the pioneering USA Instructors of the now disbanded Keysi Fighting Method (KFM). Thru word of mouth John’s classes became so big he had to switch to bigger and bigger facilities on three seperate occasions. In 2010 he opened up the current Lynbrook New York Training Facility along with his student and long time training partner Mike Simon and they have been passionately training “Adults Only” ever since. On October 26th  2011, John was tested in Spain by the Founders of KFM (both Justo Dieguez and Andy Norman) and he along with Alan Baker were the “FIRST and ONLY” Amercians to ever be awarded the KFM Black Grade (Black Belt) by both men.

In  November 2012, due to personal differences between the KFM Founders, KFM was disbanded and two new organizations were formed: “Defence Lab” under Andy Norman and “Keysi” under Justo Dieguez were established. John chose to continue his Martials Arts journey with Andy Norman and Defence Lab.

In 2012, John was promoted to the position of  North American Director of Training for Defence Lab which oversees all Instructor Training here in the USA, Canada & Mexico (Currently over 40 Training Centers in the USA alone).

On May 31st  2014, John was promoted to 2nd Degree Black Belt, USA Instructor of the Year, and inducted into Defence Lab’s Team Storm which consists of the top Instructors of Defence Lab from around the World, a great honor within the International Organization.

In addition to his ongoing training directly with Defence Lab Founder Andy Norman, John has always sought out the finest Martial Arts Instructors in their particular area of expertise to crosstrain with and expand his knowledge. He has over 19 years of continuous crosstraining (since 1996), in a broad range of Martial Arts outside of KFM/Defence Lab which include but are “NOT” limited to: Balintawak Arnis Escrima (An Art specializing in the use of impact & cutting weapons under Grand Master Bobby Taboada/Master Zacarias Taco of the Phillipines), Knife Throwing (under Master Knife Thrower Ralph Thorn), Kick Boxing & Fighting Techniques (under 7 Time World KickBoxing Champion Paul Vizzio), Muay Thai (under 5 Time World Champion Coban Lookchaomaesaitong), Pekiti Tirsia Kali (under Tuhon Mike Popolizio/Tuhon Bill McGrath) and Brazilian Jiu-Jitsu (under Professor Rodrigo Gracie). John is also a Certified Personal Trainer from NASM (National Academy of Sports Medicine) and a former New York City Police Officer from the infamous 67th Precinct in East Flatbush, Brooklyn.

John is known for his intense, personable, and realistic teaching methods. His clientele come from all walks of life and include:  Law Enforcement (Local, City, State & Federal), Security Professionals (Doorman, Executive Protection & Private Security), Business Professionals (Doctor’s, Lawyers, Accountants, etc), Blue Collar Workers,  College Students, and Regular Moms & Dads that are all looking for realistic personal protection training.  Due to his serious approach to Self Defence Training , John does NOT teach children or minors. There are no ego’s, attitudes, or delusions of grandeur at the Training Center and everyone is treated “equally” with respect. All Adults are welcome.
