We worked with Kristine on a fairly extensive remodel of our master bath and kitchen in addition to flooring for our home. Kristine is the best! She has a great eye for colors and patterns, and took the time to figure out what we needed and wanted in order to make the best recommendations for our family. Her prices are very reasonable and she was always very responsive when issues arose (as they inevitably do). Thanks to Kristine and Design Phase, we love our remodel!
