  • Ewa has been involved in translating and interpreting during numerous investigations. Her work was of an extremely high standard. During my work as an investigator I have used numerous interpreters over a range of languages. Ewa has worked tirelessly during my investigations involving Polish; her customer service is second to none. She is flexible, extremely happy, reliable and committed. Ewa is one of the most reliable interpreters I have ever worked with. She has always made herself available, her work is consistently high, and at times has worked some incredibly long hours to accommodate us. Ewa is a genuinely nice happy person, she is easy to get on with, shows an interest in her work, and has shown a level of commitment I have rarely met in others. I cannot speak highly enough of Ewa, and would recommend her for any interpretation and translation services.

  • I know Ewa through my work as a criminal defence solicitor. I have used Ewa’s services on numerous occasions to interpret for Polish national clients, both in a court setting and in meetings, as a freelance self-employed interpreter and translator. Ewa is the best interpreter I have ever used on any case. She is hard working, motivated and very committed. She is always very concerned to make sure she does the best job possible, and always provides an efficient and very professional and reliable service. She is well organised, well presented, punctual and helpful. She is very good at explaining any difficulties in translating and interpreting, and then working around any such problems. I would rate her intellectual qualities as very good. She is also very personable and easy to get on with. In my experience she is able to relate to and work with all sorts of different people, of different backgrounds and abilities. Her communication skills are excellent. I have no hesitation at all in recommending her.
