  • Principal

    Rosemary Rariden Cotter is co-founder and senior partner of Rariden Schumacher and Mio. She comes to the interior design business with over two decades of experience in residential and commercial design.

    An Oakland County native, Rosemary was raised in the country with antiques and an emphasis on decorative arts. Rosemary’s journey began as a 19-year-old newlywed, relegated to stripping wallpaper and painting their honeymoon cottage.

    After two sons born in the 70’s and a career in real estate management, Rosemary brought her interests in interior design and decorative arts full circle. After an apprenticeship she founded the design firm of Jones-Keena and in the late 90’s the firm was sold, and Rosemary continued as chairman emeritus. Within 18 months Rariden-Schumacher was formulated and launched with Jill Schumacher and followed by Michelle Mio within the year. The firm has grown, matured and completed several world class assignments.

    Rosemary has worked in both Southern and Northern Michigan, the Rocky Mountains, and South Florida on a routine basis. Rosemary’s proclivity and her strength lies in timeless traditional work accented with fine art and antiques to which she has had considerable training.

    She is regarded as an expert on color and texture, with a sense of hue that is legendary. Although her work has graced the pages of prestigious publications, she remains grounded and values her cherished privacy, dedicating precious moments to her beloved family and engaging in philanthropic endeavors close to her heart.

    Rosemary, her husband Michael a local real estate broker and their 3 dogs divide their time between Bloomfield Hills, Harbor Springs, Michigan and Naples, Florida.

    Growing up in California, Michelle’s parents always knew she would work in a field where her creativity would be put to good use. They never knew that passion would take their daughter across the country to Michigan! An accomplished collegiate golfer and student, Michelle had to decide whether golf or interior design would be her life’s path. Hands down, Michelle chose interior design! After graduating from Texas Christian University with a B.S. in Interior Design and a minor in Japanese, Michelle began working at a design firm in Fort Worth, Texas-an established company servicing some of the metroplex’s most prestigious clientele. After several years of designing in Texas, the winds of change brought Michelle to Michigan. She updated her winter wardrobe and accepted a senior design position at a local firm in Birmingham, Michigan. After spending four years with the firm, Michelle decided to open her own firm-Mio & Co., Inc. Working on multiple residential, corporate and hospitality projects, Michelle enjoyed the entrepreneurial aspect of being “her own boss.” Exactly one year later, designers, business owners and friends, Rosemary Cotter and Jill Schumacher invited Michelle to combine her experience and talent with theirs and Rariden Schumacher Mio & Co. was born. Since then, the firm has had the opportunity to design homes from coast to coast, as well as in Europe and the Island of St. John. Michelle’s work has also been featured on Detroit Fox News, HGTV and the cover of Décor Magazine. Michelle is proud to be involved with her community. Currently she is an affiliate of The Children’s Center Village of Giving and enjoys volunteering in the many events The Children’s Center has throughout the year. Michelle can often be found walking her French Bulldogs, Pippa and Pilot, through downtown Birmingham. If you happen to see them, the dogs love having their bellies rubbed!
