Fluency is not expertise — we hire for both
A merger agreement, a pathology report and a product launch can all be written in flawless English — and still speak three entirely different languages. That is why EKO 4 National Translation Service groups its 500+ professional linguists into terminological fields, and why the document you upload is never handed to whoever is free next: it is matched to a translator with documented expertise in its subject as well as its language pair.
The quality floor never moves, whatever the field: human translation by an accredited specialist, review by a second native-speaking proofreader, ISO 17100-compliant quality control, and our 100% guarantee of accuracy, on-time delivery and acceptance — in 72 languages, for clients in all 50 states, since 1991. Express delivery is available when the deadline is breathing down your neck, with tracked shipping to any address in the country.

EKO 4 National Translation Service delivers professional, accurate translation

No translator joins EKO 4 National Translation Service by accident. Before a linguist ever touches a client file, they have been recruited, vetted, interviewed and put through translation examinations in their field. And once the work begins, it never rests on one pair of eyes: translator, proofreader, editor and project manager each review the document in turn, so the 100% accuracy guarantee is earned on every page, not promised on a banner.
Most of our team members are veterans of international, multi-cultural projects. They know that a translation is finished only when it works — at the immigration office, in the courtroom, before the licensing board or in a new market overseas — and they shape every sentence with that destination in mind.
Professionalism, precision and fair pricing, backed by a 100% quality guarantee. Whatever your field, EKO 4 speaks its language.
