  • If your clinical data need to be put into words in any of those languages...

  • If your educational videos have to be subtitled...

You have come to the right place!

Antoni Maroto, ATA-Certified English into Spanish Translator



My name is Antoni, and I'm a Hispanic-American communication professional currently based in Portugal.


I work as a freelancer providing writing, translation, and subtitling services in English, Catalan, and Spanish.

While I feel more comfortable translating into Catalan and Spanish, I can also translate into English if I'm well-versed in the subject matter (i.e., life sciences).

I focus on health/patient communication and regulatory affairs, and my favorite projects are about imaging equipment and radiopharmaceuticals.
