PiLi Castro– Integrated Arts
I was born in San José in 1993. My mother language is Spanish and my second language is French. But how come French? At the age of four, I started studying at Lycée Franco Costarricien – the only French school in Costa Rica. I went for three weeks for a school exchange to France and then traveled to Switzerland, where I felt in love with nature. At 17, after discovering new landscapes and creatures, I wanted to be a biologist.
Thanks to my family’s artistic lineage, I ended up exploiting my artistic side. I developed not only visual art skills but others such as playing piano, guitar and drumming. I also consider dancing and movement as an important activity for my daily routine.
I am currently a freelance multi-disciplinary graphic designer whose delivered creative and engaging solutions across brand identity, illustration and photography. When I finished studying my bachelor’s degree in Arts and Visual Communication, I realized that I wanted to go beyond than just being a designer and working for other people. My experience and abilities to interact with children made me decide to begin a new career in art teaching. Now I see myself much more than a graphic designer or an artist: I’m a change agent who has the opportunity to open humans heart and eyes though my knowledge and art.
