What Our Clients Are Saying
-
"From the very beginning, Barrett was a full partner and solicited not only ideas of what we liked, but how we lived as a family. By doing this, it allowed her to design rooms that fit us completely - this was not about picking furniture but actually designing our home for the way we wanted to live. She and MaryBeth were a dream to work with, and they managed all the vendors, shipments, and installations, which made the entire process absolutely seamless..."

"We couldn't recommend Barrett more! We loved working with Barrett and MaryBeth. We painted, wallpapered and furnished an entire house with them. They're creative, kind, honest and hardworking. From now on, we would never make a decision without them."

"From the moment we met Barrett and MaryBeth, we've been completely blown away. We had recently purchased our dream home for our family of 4 (with two school-age kids) and we hired Barrett Oswald Designs to design the house top to bottom. We went into the project with extremely high standards given how we felt about the house itself, and they exceeded every expectation we had every step of the way."
