Sue Chan Huettl

Sue Chan-Huettl, Principal

Sue Chan-Huettl holds a Bachelor of Arts in Landscape Architecture as well as a Master of City Planning degree from the University of California at Berkeley. Prior to pursuing a career in planning, she worked for various landscape architectural firms both in California and Oregon that focused on a range of projects from residential design to the design of new communities to transportation corridors. As a city planner, Sue has worked on numerous projects across California, the U.S. and internationally, that focused on developing pedestrian and transit-oriented development plans and policies. After almost 20 years as a planner, she decided to return to smaller-scale design and joined Huettl Landscape Architecture in 2012. At HLA, Sue participates in the design process as well as the running of the firm.

Growing up in a modern home in Santiago, Chile influenced Sue’s love of warm, contemporary design. Her decision to study landscape architecture was driven by her love of art and drawing, combined with her hopes for environmental sustainability. Sue loves spending time with her kids, family and pets, as well as being involved in the larger community. She enjoys drawing, skiing and hiking. At work, she’s the “techie” of the group, and thoroughly dislikes dealing with business insurance.
