Southern California Interior Designer

Rebecca Pelletier Interiors is an Interior Design firm based in Tustin, CA serving Southern California and beyond.

We provide interior design services in Atherton, Palo Alto, and Los Gatos, and across the Bay Area from our base in San Mateo, California. Our work is hands-on and practical: we help you plan layouts that fit how you live, choose finishes that hold up to real use, and coordinate with architects and builders when a project involves permits or a construction schedule. For single family homes, we focus on room-to-room flow, kitchen and bath decisions, lighting plans, and millwork details that feel intentional without being fussy. For new construction, we step in early to review interior elevations, select hard finishes, and keep decisions organized so you’re not making last-minute calls on tile, hardware, or paint. Whether you’re starting with an empty space or updating what you already have, our goal is a calm, clear process and a home that feels considered for years, not just for photos.

From initial concept through final styling, our Southern California interior design studio delivers spaces tailored to how you live.
