For thirteen years as a partner in a widely recognized boutique architectural practice, Michael focused primarily on high-end residential and small commercial projects. Upon dissolving the firm in 2011, Wilkinson assumed an associate principal position with the Chicago office of Solomon Cordwell Buenz, concentrating on medium and high-density residential and mixed-use markets. In 2014, Wilkinson re-established his practice with partner Greg Gibson, focusing on housing, urban development, and construction.
