Laura integrates social spaces, rainwater systems and plant communities to create meaningful places where each element serves to mutually support the whole site. Outside the office, Laura pursues interests in soil ecology, meadow dynamics, and art. She spends many afternoons documenting the natural patterns of meadows and woodlands, searching for inspiration for her designs. In her home garden, Laura grows native plants, taking note of their character and durability. Born in Canada, Laura studied at the University of Toronto and the Pennsylvania State University, where she received a Masters in Landscape Architecture with a minor in ecology. She volunteers with the Delaware Valley Green Building Council, where she advocates for sustainable development practices in the Delaware Valley.
