Managing Director


I was escorting how NTI became to life from the very beginning.

I consider myself fortunate for being able to live my passion for travel, culture, gastronomy and music day by day. Working in the tourism for almost 20 years my Hungarian origins routed me through several parts of Europe to the challenging capital of Germany.

Berlin has been my new home ever since I was 19 years old. I started my career in the industry as a travel agent, followed by years of data management for the airline industry before I joined the NTI team. I appreciate working with NTI as it gives me the chance to combine my profound knowledge of the travel industry, and the opportunity to communicate in Finnish, my native language.

I was born in Germany’s beautiful maritime city Hamburg and moved to Berlin after finishing my studies in tourism management. Working with NTI I have learned a lot about Berlin’s gastronomy which is extremely diverse, multicultural and delicious.
