“Stephanie is a talented designer who turned our house into a home. She did a great job of listening to our eclectic ideas and turning them into a functional reality. Her approach is detail oriented and she is thorough and highly communicative. Can’t wait for our next project!”

“I’ve been working with Stephanie on a whole-house renovation for the past year. She takes the time to figure out what you want, then offers a number of options, along with her recommendations for which would be the most well-suited. Stephanie has a great design eye and lots of great resources both “to the trade” and retail… But the best part about working with Stephanie is that she’s a delightful person and really easy to work with.”
