"My husband and I have known and worked with Maribeth Jemmott of Certified Interiors for over ten years. During that time, I have come to greatly respect and rely upon her professional expertise and guidance. One of the best things about Maribeth is that she guides rather than dictates.Read more...
She knows how to really listen to our ideas and opinions, and has a wonderful ability to understand and interpret our taste and style to create something that is beautiful. For us, Maribeth has made designing an enjoyable and fun experience. In addition to her expertise as a designer, she can very competently and comfortably supervise and manage a team of craftsmen. When we wanted to turn our basement into a useable and pretty space, Maribeth designed two adjoining rooms with a half-bath, including wonderful storage areas, and acted as general contractor from start to finish. When we were ready to renovate our kitchen and two bathrooms, she was our natural choice to assist us in selecting cabinetry, fixtures, lighting, appliances, and countertops."

She can do it all well - kitchens, bathrooms, window treatments, furniture, and painting. Thanks, Maribeth!"

"Maribeth, I was thinking about three words to describe you and it is really hard to pick out just three! Inspired came immediately to mind because you always have such great ideas and have such good vision for design.Read more...
Innovative came next because you are so good at solving problems in rooms and make it seem so effortless even though I know it isn't. I keep thinking about the built ins in my new family room. I was not able to put to words what I wanted but you were able to help me communicate what I wanted and a picture came about... and you also took all of my furniture from Lauren Lane and made it work in my new place with just minor adjustments. You took the window fabric I loved from the premade treatments and made that work as well - which I know was not easy! Artistic because every space you work on is beautiful and reflects the owner and the taste of the owner. That is really hard to do and you do it with such grace and ease. Let me just say I could add clever, gifted, visionary, imaginative, resourceful, knowledgeable, inventive - you get the picture I just could go on and on and on..."
