Originally from Louisville, Ky, Elizabeth is an experienced professional who has steered her architectural career toward improving building technologies and efficiencies. She is a Registered Architect, with active licenses in the states of Pennsylvania, Kentucky, and Florida. As an architect, She has a strong interest in education, research and service. She believes the building design and construction industry is ready for systemic changes.
She is a lecturer at the University of Pennsylvania, and holds board positions at numerous institutions within her local community. Elizabeth is a former trustee and board member of the Gladwyne Free Library, where she oversaw the replacement of both the roof and heating system. She is currently an active Vestry member at St. Christopher's Church in Gladwyne, where, as property chair, she is coordinating the installation of a state of the art geothermal heating and cooling system.
After founding and growing her own architectural practice, Elizabeth and her partner, Yair Keshet, pioneered integrating operating rooms into physician-owned medical practices. With the firm’s guidance, practitioners are able to make the cost and risk analyses necessary to grow their practices and regain control of their surgery logistics. The firm now consults and designs nationally, with built work in multiple states.
Elizabeth is a lecturer, her courses focus how individual buildings aggregate into neighborhood scale effects, with storm water management of the site as a key theme. In 2022, she was the recipient of the Holmes Perkins Teaching Award. Her course, ARCH 3010, uses the history of the Mill Creek neighborhood as context for new design proposals. Students actively track and monitor green roof samples for their storm water performance, bring the small scale building technology into the context of the neighborhood. Her research and topological modeling was featured as part of Adam Levine's "Lost Creeks of Philadelphia" Exhibition at the Philadelphia Athenaeum in 2026.
