She was raised in a family of artists, as being the daughter of Narcís Puget Riquer and granddaughter of Narcís Puget Viñas. Guillermina began painting with her father when she was very young. Although her style has evolved over time, the artist has remained faithful to abstraction, which has helped her to express her inner world. In addition, she usually opts for acrylic paint, which, thanks to its drying so fast, allows her to better reflect immediacy.
