Kate Gillespie '88 MSUP
Kate G.jpg

Kate Gillespie '88 MSUP
Director, Gillespie Consulting

Concerned about improving the built environment, Kate left a career as a public school teacher to veer into architecture and urban planning. Kate’s interest in public spaces and public buildings enabled her to experience the power planners have to influence planning regulations as well as the impacts planners have on improving our neighborhoods, environment, and public health. A computer user since 1979 (before many readers of this bio were born), Kate embraced computer graphics, GIS, database development, CAD and 3D design. Still a teacher at heart, she is passionate about hands-on public involvement, and using “teachable moments” to help non-designers get involved with our profession. One of her proudest accomplishment was leading a band of architects in creating the Snow Sculpture event in 1983 as part of Anchorage Alaska’s winter Fur Rondy event–this community activity was created to encourage architects and contractors to have fun together, while introducing the community to architecture in a fun way with a naturally abundant material! http://www.furrondy.net/events/snow-sculpture-championship
