"Kate has the eye. She designed my investment penthouse. It was originally boring and very white without accents and she gave the entire place a facelift. Kate does it all. She shops for you, provides multiple options and has an artistic flow. She tracks orders and ensures things get properly completed no matter how difficult the task at hand may be. 5 out 5."
