Who we are?
Chief Instructor
My name is Sahanshil Rai (Sonny). I’ve been training martial arts since the age of 7. Through my journey in martial arts, I’ve had opportunities to meet great people and study various different martial arts.
As I got older, I became more curious towards the aspects of self-defence. Thus, I became a Krav Maga Instructor at 123 Krav Maga after many years of being a student and assistant instructor.
With a demand for kids classes and a lot of interest in helping and aspiring children, we have established 123 Martial Arts for kids.
Our goal is to teach them the values of martial arts while improving their mental, physical and social well-being. We believe that every child is special and with the right guidance and training they all can develop a great character to become the best version of themselves in the future.
Instructor
Andy discovered Krav Maga whilst living and working in the US after many years spent training in traditional martial arts including Tae Kwon Do and Kung Fu. He was immediately impressed by Krav Maga’s highly-effective self-defence and combative techniques and the clear logic underlying the system.
On returning to the UK in 2012 Andy continued to train Krav Maga under Nick Maison and 123 Krav Maga Founder, Kris Szczepanski. After several years of dedicated training, Andy was awarded his Instructor diploma by Master Tomasz Adamczyk in 2018. He is also a qualified Kids Krav Maga instructor and a rugby coach.
Instructor
Dariusz is a dedicated martial artist, certified personal trainer and Krav Maga Instructor. His background include Kick boxing and hand to hand combat from the military, bringing discipline and real-world knowledge to every class.
Being a father of three, he understands the importance of patience, structure and fun when working with kids. When not, teaching or training, you’ll find him hiking in the mountains, travelling, or simply enjoying outdoors with family.
In 2025, under the watchful eyes of founder Sonny and Piort from Academy Krav Maga, Dariusz completed his Krav Maga Instructor Course and is teaching both adults and kids programme since. He also holds a Certificate in Sports Nutrition.
Assistant Instructor
Marek started his Krav Maga journey in 2021 with 123 Krav Maga. He wanted to learn practical self-defence skills and build confidence that keeps him and his family safe in real life situations.
“Training gives me strength, discipline and mental focus, helping me stay calm and prepared under pressure” - Marek
“I enjoy teaching kids because it empowers them with valuable skills, boots their confidence and encourages respect and resilience from an early age”
- Marek
