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. She is former member of the Karmanos Cancer Institute’s Partners Committee, serving as President and Executive Committee Co-Chair. Michelle has also been involved with the Restore Foundation and proudly supports the Michigan Humane Society and Detroit Children’s Fund. 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, Gus and Gertie, through downtown Birmingham. If you happen to see them, the dogs love having their bellies rubbed!
