Defensive Kombat Krav Maga

DEAN-KHANH NGU-YEN

 

Dean-Khanh is an internationally trained martial arts and self defence instructor whose journey began in 1984, at the age of eight, and has taken him to numerous countries to study, train and teach in places like Israel, Philipines, Thailand, Japan, Hong Kong, Indonesia and to the eastern Australian states of Queensland, and New South Wales.

 

Dean holds a 6th Degree Black Belt in the Gadi Kenpo Jitsu System awarded to him in 2021 by GM Guy Skornik and Major Itay Gil. In late November 2025, he was also graded and awarded a 5th Degree Black Belt in Krav Maga by the highly renowned Israeli Combat Major, Professor and Doctor Itay Gil, the founder and 8th Degree Black Belt of the Protect Krav Maga System. Dean is also the official Western Australian representative of the Federation of Israeli Martial Arts (FIMA).

 

Back in 2020, Dean was awarded the 5th Dan Black Belt Rank in Tae Kwon Do under 9th Degree Kukkiwon Grandmaster Nghia Trong Truong, with whom he has trained continuously since 1984. Across more than 42 years of martial arts training, Dean has also cross-trained in numerous other disciplines, including Boxing, Brazilian Jiu-Jitsu, Escrima, Hapkido, Kali, Karate, Kickboxing, Jeet Kune Do, MMA, Muay Thai, Silat and Wing Chun.

 

Dean has been professionally teaching martial arts and self-defence for over 25 years, beginning in June of 2000 at government-based high schools in Sydney, NSW, Australia.

 

After returning to Perth, Western Australia in 2002, Dean shifted his focus on training towards the tactical elements of mixed martial arts and eventually the self-defence components of Krav Maga in 2008. His training and teaching prioritises survival, real-world application, and personal safety, as opposed to competitive tournament-based martial arts.

 

In mid-2011, Dean opened up and run his own tactical mix martial arts and self defence academy in Bayswater sharing the space with his Combat Skills and Boxing coach Mannie De Matos, while also operating his private personal one on one training sessions from his home studio in Morley, catering to individuals who prefer the one-on-one interaction. 

 

Dean is approachable and welcoming to new students and clients of all genders, ethnicities, and ages who are eager to learn practical self-defence, self-protection skills for reality base scenarios, including home invasions, public assaults, attacks during commuting, workplace and domestic violence situations.

 

In addition to accommodating FIFO workers and everyday 9-to-5 professionals, Dean’s current and past clientele include military personnel, security professionals, correctional officers, law enforcement personnel, lawyers, pilots, doctors, nurses, ambulance officers, paramedics, highschool and college staff /students, all of whom have sought his training and self-defence tactical methodology in Krav Maga.

 

If you are seeking personalised one-on-one training, Dean is committed to empowering and building confidence, to ensure that you are equipped to confront and stand up against physical bullying, verbal threats, and potential violent assaults, whether the assailant is armed or unarmed.

 

His long commitment to excellence is supported by his 25 years of professional instruction (since early 2000) and 15 years of successfully running his business full-time (since 2011), both from his private home studio in Morley and his academy out in in Bayswater, Perth, Western Australia.

 

Dean continues to stay current with developments in the combative field and seeks out internationally renowned martial arts instructors such as JKD Guru Dan Inosanto, Benny the Jet Urquidez and Major Itay Gil. He has remained a student throughout his lifetime and is constantly looking at ways to improve and enhance his training delivery. He regularly updates his training and qualifications and enjoys his training trips overseas to improve his craft and attain further knowledge from other experienced masters, guros and grandmasters.
