Jennifer Crawford-COII Interior Designer

I am originally from California, and moved to east central Illinois about 16 years ago. My husband and I live on a small farm, raising our two young daughters. We have 2 dogs, 2 cats and chickens. I love to travel and cook, try new foods and recipes.

I find inspiration in design from nature and my travels to achieve the desired outcome for my clients. I prefer to use local producers/craftsmen for materials and it is fun to create unique pieces. I have ample knowledge in the building material/construction industry which allows me to make recommendations specialized to each project. I have a focus in kitchen and bath design for 13 years. If we can dream it, draw it, we can build it.
