Liesl Geiger-Kincade began her career studying architecture's most intangible quality, light. After earning her Masters of Architecture from Yale, where she received the Anne C.K.Garland Award, Geiger explored the subject with architectural glass designer James Carpenter, working on notable public buildings around the world. After, she undertook a Fulbright Fellowship in Helsinki, Finland, where she spent a year studying glass and light in architecture at the University of Industrial Arts, as well as in the buildings of architect Alvar Aalto.

Before forming her own studio in 2003, she apprenticed with New York architecture firms including Robert A.M. Stern Architects, Peter Marino Architect and Peter Gluck and Partners, where she designed everything from modern Madison Avenue boutiques and Brooklyn townhouses to classical regional farmhouses and stone grottos in Napa Valley. Along the way, she was assembling the building blocks that would not only inform her practice, but also her book, The Essence of Home: Timeless Elements of Design, which was published by The Monacelli Press in November, 2007.

Geiger received a BA summa cum laude from Yale and afterwards studied architecture in France.

Geiger first fell in love with design in grade school. As a student in a Frank Furness structure (the former Bryn Mawr Hotel, outside of Philadelphia), she spent 12 years experiencing and sketching the building's stone, glass, and metal handcraft. The Furness spaces, such as the voluminous main residence hall capped with a red slate roof and their details remain engraved in her mind.
