I started interpreting in 1990 together with my wife Aven Abdulkader. Those days only very few interpreters in Kurdish Sorani language existed and there was a high demand for them. The year 2009 was a proper time to establish Tulkkikeskus Ästerä Oy, meaning “a star” in Kurdish Sorani language.

Now our language selection includes already over 70 languages. We have established our position as a reliable operator in the language and interpretation field and we attempt to provide personal service for all of our customers.
