Born in Haiti in 1982, Chevalier lives and works in New York City (NYC). Mildor grew up watching his father in his carpentry shop and his mother teaching his students macramé and drawing patterns to make clothes, so he developed a passion for the art. In 1999, he took drawing and painting classes at the Grotte Des Arts Plastiques school in Port-au-Prince. A year later he moved to the Dominican Republic and in 2010 obtained an Associate Degree in Fine Arts from the School of Design at Altos del Chavón. After graduating, he received a full scholarship to study at Parsons the New School for Design in NYC, where he obtained his Bachelor of Fine Arts. He has a Master of Fine Arts from the Fashion Institute of Technology in NYC.
