About Me

I am a 26-year-old professional kickboxer and Muay Thai fighter from Helsinki. I am determined and persistent by nature. Behind my athletic background, however, is a social and gentle personality that gets along well with different kinds of people.
I have a total of twelve years of experience in martial arts, including ten years of competing and eight years of coaching. My experience in kickboxing, competing, and coaching both groups of various sizes and individuals demonstrates a strong level of expertise and a deep understanding of the diverse demands of the sport.
Through my experience, I have also gained in-depth knowledge of kickboxing techniques, training programs, and injury prevention, which enables me to provide high-quality and safe coaching to my clients.

Reviews
Training with Niko is fun, effective and professional! Niko takes all of his clients' individual needs into account, whether it's their physical condition or a specific issue. My son has also taken a private session, and Niko is absolutely great with kids too.

Niko is a relaxed, fun and professional coach. He considers each individual's level and goals, while still encouraging you to push beyond your limits. He's flexible with scheduling and always patient. The workouts are tough, but you're guaranteed to feel great afterwards! You'd be hard-pressed to find a better coach!
-Sofia & Karin-
We´re a couple in our thirties who were looking for a new active hobby to enjoy together - and we found it in Muay Thai with Niko´s coaching! We started private training sessions in the fall and can warmly recommend them to everyone! The sessions have been varied and perfectly suited for beginners, while still being challenging enough to keep things interesting.Niko's coaching combines technique and hands-on practice in a great way, which has helped us improve both body control and overall fitness. Each session is tailored to us individually, which makes the experience especially rewarding.
Thanks to Niko's focused coaching, we've noticed that same determination growing in other areas of our lives too. Despite his young age, he's a true role model for anyone. Niko is a fantastic person — a clear and motivating coach.
We highly recommend these sessions to anyone looking for an effective and fun way to stay active!
