Robb Osaba

Robb Osaba is a storyteller at heart, fluent in both English and Spanish, who believes every home has a soul—and that design is the language that brings it to life. A Georgia native with Cuban roots, Robb has spent years immersed in the rhythm and energy of Metro Atlanta, helping homeowners transform ideas into inspired, livable works of art.

At Mosaic Design + Build, Robb is the welcoming bridge between clients and the design-build process. With a thoughtful, hands-on approach, he walks alongside clients from the first flicker of conversation, weaving ideas into form and collaborating with project leads and the design team as each project begins to unfold.

Robb’s path began with Warrior Contracting, the company he founded and grew from weekend projects into a full-scale residential design-build firm. Over 15 years in the field, he honed the delicate balance of form and function, heart and hustle, all through the lens of an unparalleled client experience. While his toolbox is still well-used, today his greatest tools are expressive communication, intuitive creative design and a deep well of construction know-how.

With a Bachelor of Arts in Business Marketing and Pre-Law from Oglethorpe University, Robb—a true jack of all trades—is known for his meticulous attention to detail, innate sense of design, and effortless threading between grace and grit.

Robb lives in Brookhaven with his wife and their four sons. When not immersed in design or collaborating with clients, you’ll find him cooking, mountain biking, making music, or chasing the sunset with his family.
