“These ladies worked professional magic — we pinch ourselves everyday that it’s our home! Stephanie and Melanie are a top notch team and complement each other beautifully. With impeccable communication they kept our project organized and on track, coordinating everything from samples to installation. When the inevitable glitches arose, Stephanie and Melanie handled it with common sense and professional expertise. Throughout the project they honored our budget, time, home, and lifestyle as if it were their own. We spent years yearning for a better kitchen, but were leery of the process. We can honestly say we’d do it all over again in a heartbeat — we look forward to working with them again!”
