Castillo's work refers to a cultural past and contemporary present, fusing a hybridized aesthetic to engage issues about migration, historical trauma, identity, and memory. His narratives express a multifacted, interlocking and non-linear approach. Consequently, the body of work revises and casts new personal interpretations on memory-building as a form of resistance, political commentary and healing.

My work depicts a critical narrative of historical, cultural, and personal experience. Using drawing as a personal act of revision my work explores the role of storytelling through Pre-Columbian mythology, popular folklore and elements sourced from visual and vernacular culture, all intertwined through a personal lexicon of imagery that is constantly being developed and revised over time.
