About me

Jose Luis Díez Lerma

Jose Luis Díez Lerma

Certified French-Spanish translator

I was awarded a degree in translation and interpreting from the University of Granada in 2002, the year I was also appointed as a certified French translator by the Spanish Ministry of Foreign Affairs (my signature is recognised by the French Consulate in Barcelona). After spending a long period living in different European countries (including six years in France, where I combined lecturing at the François Rabelais University in Tours with work as a translator and interpreter in Tours-Orleans High Court). I decided to settle in Barcelona in 2010, where I played an active role on the governing board of the Professional Association of Translators and Interpreters of Catalonia (APTIC). I am currently an associate member of the Professional Association of Court and Sworn Interpreters and Translators (APTIJ).

My customers’ opinions

Recommander Jose Luis pour de la traduction français-espagnol c’est comme recommander Leo Messi pour un poste de footballeur… tout est dit.

Molt content del tracte i la professionalitat d’en Jose Luis! Ens va traduir amb rapidesa uns documents que necessitàvem amb certa urgència per emigrar a Québec, a un molt bon preu, i responent ràpidament per email a totes les nostres qüestions. Tot els documents que ens va fer ens han servit per fer els tràmits necessaris ara que ja estem a Québec, sense problema. Molt recomanable!
