We are Liden & Denz


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

On behalf of Liden & Denz, I would like to welcome you to our Russian language programmes in St. Petersburg, Moscow, Irkutsk and Riga. The range of courses we provide offer you a wealth of opportunities to study this historic language in a way that best suits your needs. And with our varied activity programme designed to make the most of the cultural opportunities on offer, your understanding of Russian will extend beyond simply the language.

Our schools are located in four of the region’s most historic, beautiful and culturally rich cities:

  • St. Petersburg was the jewel of Imperial Russia and is a UNESCO World Heritage site
  • Moscow is Russia’s economic powerhouse and Europe’s second largest city
  • Irkutsk is the capital of Eastern Siberia and a gateway to the Baikal region
  • Riga is the beautiful Latvian capital, full of charm and history.

These four fantastic cities are the perfect locations in which to learn Russian, while immersing yourself in the culture and enjoying the legendary Russian hospitality.

I co-founded Liden & Denz in 1992 and it is now one of the oldest, privately-run Russian language institutes.
Our institutes are regularly inspected by international accreditation bodies and operate a transparent quality assurance scheme. I am proud of the worldwide reputation we have gained as a first-class training facility, which has largely been thanks to the hard work and dedication of our staff.

We hope you choose to study Russian with us and, whichever centre you choose, you will be assured of a warm welcome.

Walter Denz

Liden & Denz is owned by co-founder Walter Denz, who grew up in Zurich, Switzerland and graduated from the University of St. Gallen (HSG) in International Relations in 1989. He then moved to London to enroll to an M.Sc. degree in Political Theory at the London School of Economics and Political Science, and finally settled in early 1992 in post-communist Russia. Together with his partner and friend Sven Lidén, he set up the Liden & Denz Language Centre in St. Petersburg, one of the first private institutions for the teaching of Russian as a foreign language. Later, Walter ventured into tour operating (outbound) and, in 2004, opened the first sister school in Moscow, followed by Riga (in January 2014) and Irkutsk (in 2016).

From 2008-2011 Walter was president of the International Association of Language Centres IALC and since 2012 he is vice-chair of Eaquals, the international accrediting body for language training institutes. He also is chairing the board of the Deutsche Schule St. Petersburg. With his family, Walter lives in St.Petersburg.

Since 2012 the company is run by Julia Voevodina, who gradually built her career with Liden & Denz after graduating with honours from the St.Petersburg University of Economics as a specialist in Strategic Marketing in 2005. Before her appointment as CEO, Julia assumed different roles in both St.Petersburg and Moscow and gained a lot of experience in the spheres of services and marketing. Human resources and operational management are her main priorities. Julia is a big fan of the study travel industry and global education issues.
