Proem Studio is a Los Angeles-based interior design firm founded in 2017 by Ashley Drost and Marie Trohman.

We approach all projects as the beginning of a new chapter, be it a personal or professional endeavor, and strive to create design that is fresh, inviting and highly personal. We emphasize quality, support small businesses and source vintage from all over the world. PROEM STUDIO brings Ashley and Marie's respective backgrounds in styling, art, and set design to residential, commercial and hospitality projects in Los Angeles and New York.
