Communicating is an art. Doing so in different languages is a science.

Translation, interpreting and transcription.

TISA: 40 years of experience in the science of translation.

Translation, interpreting and transcription services that maintain the original meaning, sense, tone and emotion of words, whatever the verbal or written language or signs used to convey them.

Guaranteed quality.

TISA guarantees the quality and accuracy of its translations and interpreting services. Checks are made to ensure the accuracy of terminology, spelling, syntax and grammar and the overall consistency of texts. TISA uses latest-generation technical and IT resources.
