She has been quoted in decorating articles in publications throughout the Midwest and had her personal home featured in the Milwaukee Journal/Sentinel and Door County Living. "Marilyn makes an effort to get to know her customers. We were looking for style and comfort and she did everything possible to help us achieve our goals. We've always been very happy with the work she’s done for us and easily recommend her to our friends and neighbors.

To provide each client we have the privilege to serve with the feeling that they have encountered something special.

To offer unequaled value and exceptional interior design while delivering world-class service.

To inspire our clients to discover their individual style and exceed their expectations in delivering products and services.

To treasure our customers and community that we are so fortunate to be a part of and give back whenever possible.


Here at Sister Bay Trading Company we believe community service lifts all of us to a better place. Generosity isn’t about just donating a percentage of sales on a certain day. It’s about living and breathing “giving back.” That’s why employees have served on the board of directors of the Door County Humane Society, the Sister Bay village board and donate to other local non-profits. From decorating the interior of our non-profit health clinic to providing internships for local high school students interested in design, the act of giving locally starts with the generosity of each member of our team and spreads across Door County to make our corner of the world a special place! In-store events have lifted some of our favorite charities. We encourage you to join us in supporting:

D.C. Humane Society, HELP of D.C, D.C. YMCA, Hardy Gallery, Nor Door Children’s Center, Altrusa Club of D.C, Gibraltar Schools, D.C. Maritime Museum, Feed and Clothe My People, Door County Habitat for Humanity, DC Land Trust, Altrusa, and 100 Women Who Care
