Senior Associate | Director of Interior Design
Sarah Bay has the heart of an artist. Her passion is simple: to weave beauty and elegance into the physical world. That’s why it’s second nature for her to approach each project from a creative, holistic perspective. When creating, she considers all the aspects of design—everything from the interior aesthetic and function to the exterior and outdoor environment of a building. Her process starts with active listening. Next, she embraces collaboration with architects, contractors, and consultants, all of which leads to innovative solutions that impact those who inhabit the designed space. For Sarah, the ever-evolving landscape of interiors is an attractive and inspiring challenge to her competitive spirit, and she relishes the opportunities it affords to continue to cultivate her design expertise. During the last 10 years her experience includes hospitality, restaurant, and corporate built projects, national brands, as well as Fortune 500 companies.
She holds a B.F.A in Interior Design from the University of North Texas and an M.B.A.from Colorado Technical University. When she’s not hard at work, she’s involved in IIDA, CoreNet, and Ladies in CRE. She also enjoys running, painting, and serving at her church, plus caring for her greyhound, Kobe
