Born in Guatemala City in 1976. Even though Barrientos is an elementary school teacher and has a college degree in Art and Social Sciences, ever since he was a boy he has been exposed to his father's sculpture studio which is where his love for sculpture began. Later he studied sculpture with several renown masters in Guatemala. His interests lately has been to create pieces with recycled materials: metals, plastic, toys, which he tears apart and combines in a spontaneous spree. Ingenuity, patience but also lot of play during the creative process end up in aesthetic and conceptual forms with profound meaning.
