I was born in Calella (Barcelona) in 1956, and nowadays I live in Vilassar de Mar (Barcelona). Since I was a child I have been fascinated by painting and I think I'm a self-taught painter because, despite I was taught drawing at Primary School, I have acquired my knowledge thanks to my environment. Painting is my own way to express myself. I can shape my inward in the canvas with the essential help of the palette knife and the colours. As a nature’s lover and great observant, my environment has always been my source of inspiration. At present I devote myself exclusively to painting, my true passion, and that is why I feel extremely fortunate.
