OUR STORY

A full-service interior design studio rooted in craft and shaped by design.

Founded by wife-and-husband team Samantha and Casey Tosti, Tosti Design began as a shared creative pursuit rooted in a love of architecture, craftsmanship, and the details that make a house feel like home.

Today, Samantha leads a growing team of designers who carry that same spirit forward, blending form and function, precision and warmth. Drawing from her architectural background, she creates homes that feel comfortable and built to last, where natural materials and thoughtful layers reflect the people who live there.

From new builds to full-scale renovations, the studio approaches design as a partnership — with clients, builders, and craftspeople — to bring thoughtful, lasting spaces to life.
