Terry Phelan, AIA

Director, Sustainable Practice

Terry is an insightful and intuitive architect dedicated to expanding green building practices through awareness, education, and action. Throughout her 30+ year career, Terry’s passion and reverence for nature and the environment have inspired her to effect real change in the A&D industry through cost-effective, restorative, and high-performance design.

Terry takes an education-first approach, focusing on outreach and mentoring to accelerate growth in the deep green space. A thought leader in sustainable design, Terry is a sought-after contributor to and creator of conferences, workshops, podcasts, and more. She has been recognized for her dedication to ecological design and business practices.

Always taking the road less traveled, Terry apprenticed for many years before taking exams to become a licensed architect. She has worked on a variety of projects at many scopes and scales, including, single-family residential, small commercial, adaptive reuse, cohousing, and more.

In her life outside the office, Terry embraces joy and health, growing food and cooking for others in the small cohousing community she calls home. She enjoys running errands by bicycle in Old Town Issaquah and exploring the tranquility of the deep woods of the Olympic and Cascade Mountains.
