We’re an interior design firm based in San Rafael, and we’ve had the pleasure of working with Gannon Construction Company on three projects—one commercial wine bar and two residential homes. We can’t say enough good things about their team. Gannon is professional, communicative, budget-conscious, and consistently delivers on time. They are honest, realistic, and an absolute joy to collaborate with. I truly wish we could work with them on every project. Their craftsmanship is exceptional, and their support from start to finish—combined with a discerning eye for detail and quality—sets them apart in every way.
