I hired Prime Designs by Nancy in 2014 to do a complete remodel of the interior of my restaurant. Nancy was full of ideas and enthusiasm for the project and once the basic decisions were made she took over and made things happen. She dealt with all of the contractors and suppliers so I could continue to run my business. i ended up with a new fresh and contemporary look to my dining room and my customers loved the new look. My business took a big jump with the remodel and has stayed up over pre-improvement levels. I would hire Prime Designs by Nancy again in a heart beat, she does excellent work with good customer service.

Nancy did a great job when we were building our house; from selecting paint colors, to accent tiles, draperies, and even some faux finishes on walls and ceilings. She is very energetic, friendly, and easy to work with. Nancy listens to your ideas and makes suggestions when you are stumped. Enjoyed working with her on our new home.

Nancy was awesome. She helped us work with finishes we already had in our home and our dreams for future home improvements. Her suggestions were more up to date and timeless, compared to what we were seeing on the home improvement shows. We have recommended her services to family and friends.

Prime Designs by Nancy is efficient, honest and reliable. From the first time you call Nancy, she starts her creative process, and sees all the possibilities. She gets a vibe from her clients and their homes in a way that is only unique within her. She has impeccable taste and out of the box ideas, which will set your home apart from others. At the end she leaves you with a home you’re happy to go home to and grow with.

I have used Prime Designs by Nancy for projects at both my office and my home. Nancy did the total design work for my office when it was built 6 years ago and I hired her to remodel my home "man cave" which consisted of a new bar, game room and media room. Her work is outstanding! She is creative beyond my expectations and ran both projects from beginning to completion while keeping me in the loop every step along the way. I highly recommend Nancy's work and I will use her again!!
