Roser studied Translation and Interpreting at the Universitat Autònoma in Barcelona. She did a minor in History and Linguistics in Amsterdam and fell in love with this city. She spent two more years studying Voice Over and Drama Studies. After a decade working in tourism, she became a tour guide. Her first focus was the History of Amsterdam, but it spread to the rest of the country. In 2013 she began guiding curious minds through the Jewish History of Amsterdam. In 2019 she got her diploma as a National Guide, while working at the Anne Frank House. She is now halfway through her Art History bachelor's degree at the Universiteit van Amsterdam. You can find her at the Museum of Modern and Contemporary Art and Design in Amsterdam, the Stedelijk Museum.
