She has led or contributed to a number of years-long projects, including LA Metro Councilmatic, the Illinois Public Salaries Database, and WhoWasInCommand, and takes great pride in working in partnership with longtime clients to improve upon them. In her spare time, Hannah enjoys home improvement, eating just about anything, and simply existing in the company of her husband, pets, and plants.
