About Us

Our story

Dora Wirth (Languages) Ltd. (DWL) is a specialist language service provider to the Life Sciences industry. Since 1962 we have worked with the world’s leading pharmaceutical companies to translate documents that help bring ground-breaking medicines and devices from clinical trial to market.

Our Mission

DWL is committed to delivering world-class translation solutions within agreed timelines and in line with well-established ISO and industry standards. We encourage clear communication with our clients to establish their requirements, and use our experience to get the translation process right, first time round. We pride ourselves on our knowledge and flexibility, which help us maintain our high standard of service, no matter the size or complexity of a project. We achieve this by:

  • Providing a service tailored to each client, based on their specific requirements
  • Maintaining lasting business relationships based on trust, mutual respect and standard of service
  • Ensuring effective and reliable project management with a single point of contact for all projects as required
  • Operating within our ISO 9001 certified Quality Management System (QMS), updated and reviewed on a regular basis

Our History

DWL began as a one-woman operation by Dora Wirth, the mother of our current CEO Samuel J. Wirth. Born in Moscow in 1916, Dora left her native Russia during the 1919 Counter-Revolution. She moved to Warsaw with her family before settling in Danzig until the mid-thirties.

Dora came to England in 1935 speaking Russian, French, German, Polish and English. She capitalized on her passion for languages, and worked at the Daily Express during the Second World War monitoring speeches by Hitler and Stalin. In 1962 she founded Eurolink Limited, a translation agency which, in 1964, became Dora Wirth (Languages) Limited. The key to her success was a combination of linguistic prowess, business acumen and a strong work ethic: qualities we still rely on at DWL today.

In subsequent years, DWL has grown to be a key player in life sciences translations. Our team of experienced project managers oversees the needs of hundreds of life sciences customers, from Big Pharma and CROs to universities and start-ups.

Our Expertise

Our approach to life sciences translation is built on a solid foundation of freelance and in-house medical expertise. We rely on a network of over 1000 translators and revisers selected not only for their linguistic skills, but also their specialist knowledge and experience. Most linguists translate into their mother tongue only and are based, wherever possible, in the country of their target language. This ensures that they keep up-to-date with both changes in the language itself and industry developments.

All newly recruited linguists are subject to DWL’s rigorous evaluation procedures and their performance is continuously assessed under the supervision of our in-house Medical Director. We also operate a strict confidentiality policy given the sensitive nature of the translation work we undertake.

Our network of linguistic experts includes:

  • Medical and pharmaceutical translators
  • Physicians
  • Biomedical and chemical scientists
  • Regulatory affairs consultants
  • Lawyers and legal experts
  • Financial and commercial specialists
  • Computer Aided Translation (CAT) consultants and terminologists
  • Desktop Publishing (DTP) professionals


DWL’s in-house medical expertise is provided by our Medical Director Dr Iain Matheson, a physician and experienced translator, who is always on hand to resolve medical and linguistic queries, and to monitor DWL’s global supply chain of translators and revisers.
