We are Liden & Denz - Learn Russian in Russian & Denz

Welcome to the world of Russian – Welcome to Liden & Denz!

On behalf of Liden & Denz, I warmly invite you to join one of our Russian language courses in St. Petersburg, Moscow, Irkutsk or Riga. The idea to organise Russian language courses in post-Soviet Russia must have come to Sven Lidén and me over a glass of vodka in a bar not far from our alma mater in St.Gallen, Switzerland. 

As early as spring 1992, our first willing learners ventured to St.Petersburg. The Russian Roaring Nineties had not even really begun! Today I am grateful for many exciting years in what was then a foreign country, now my home.  

I owe my continuing enthusiasm for the Russian language exclusively to my teachers. Our team of more than fifty Russian language teachers will also inspire and carry you along. 

I look forward to your visit to St. Petersburg, Moscow, Irkutsk or Riga.

До встречи!

Walter Denz

Liden & Denz is now owned by co-founder Walter Denz, who grew up in Zurich and graduated from the University of St. Gallen (HSG) in 1989 with a degree in International Relations. This was followed by a Postgraduate degree in Politics at the London School of Economics and Political Science. In early 1992, he settled in post-Soviet Russia. Together with his friend and partner Sven Lidén he founded the Liden & Denz Language Centre in St. Petersburg as one of the first private language schools in the country. Moscow followed in 2004, Riga and Irkutsk in 2014 and 2017 respectively. Walter Denz was President of the International Association of Language Centres IALC, Trustee of the accreditation authority Eaquals and until recently also Chairman of the Board of the German School in St. Petersburg.
