  • “I hired Krystle, on two occasions. One of the best decisions I made after buying my homes. She selected the colors, furniture and lighting fixtures for every room. She was attentive, listened to MY style and executed. My home was made warm and comfortable. I received many compliments too. I really enjoyed the experience.

  • "Look no further! The O’Neill Casa is all you need! I contacted Krystle for help choosing a paint color for my open dining/ reading room. After many trials of paint swatches and samples I tried to pick on my own, I knew I needed some professional help! She was quick to respond, arrived on time, and confidently helped me get the right color for the space and my taste! I’m so happy with the results! Highly recommend!!

  • "After a downsize and a difficult move, Krystle helped me to make my new place a home. She found the perfect furniture to fit and the decorations gave it a warm and welcoming feel. I can't express my appreciation with all she did to make this an easy move for me."

  • "Krystle is a gem and has such an eye for interior design. She has been helping me for years with projects around my house and always has a keen eye to help me with exactly what I want. I am terrible with color and Krystle has helped me choose color for so many of my homes and has been spot on. She helps to execute whatever your vision is. I absolutely adore her and appreciate her keen eye."
