Mardie combines experience in architecture, development and finance with a passion for creating inspired affordable housing. After earning her architecture degree from Rice University, she spent five years developing affordable housing to revitalize the Fifth Ward, Houston’s lowest income neighborhood. There, she co-created an exhibition and demonstration project, “16 Houses: Owning a House in the City” in partnership with the Rice School of Architecture and Diverse Works Artspace. As a result, Mardie recognized the need for creative financing and for building bridges across disciplines to help make cutting-edge projects a reality. After earning her MBA from Harvard Business School, she served as a Harvard fellow at Boston Community Capital, a nationally recognized CDFI. Mardie moved to the Bay Area in 2003 to be the Director of Real Estate Lending for Opportunity Fund, making investments in affordable housing and community facilities throughout Silicon Valley. Here, she was introduced to many people committed to creating a brighter future for the residents of Agnews Developmental Center, which led to the launch of Hello Housing in 2005. After 16 years as Hello Housing’s President, Mardie transitioned into a board chair role in the spring of 2021.
