“Beautifully designed! Terri listens as a designer. She was able to pick up on what I like and even presented me with options I never would have considered on my own. She was also incredibly timely, communicative, and organized with her presentation. I trusted her and I love the design she gave me. Elegant and welcoming."

“I can’t say enough kind words about TBI. I asked for a design that would be relaxing but sophisticated, and Terri delivered that and more. Every one of my clients has remarked on how wonderful my new spa looks. Whether it’s the furniture, flooring, paint color, wall paper choice or decor items, it all beautifully works together in one cohesive design. I couldn’t have done it without her expertise. I would recommend her design services to anyone because she brings so much knowledge and value. You’ll be happy with the finished product.”
