Laurel Macdonald, Landscape Architect and Principal-in-Charge, established this firm in 1982 and has over 38 years of experience in master planning and design for medical centers, education campus’, healing environments, housing, mixed-use, and planned communities.

From the beginning of her career, Laurel has had a solid understanding of the public process and project implementation. Her experience includes a variety of projects in which she strives to employ sustainable design solutions. The scale of her work varies from developing the first eco-roof in Portland to preparing a 10-year development master plan for Samaritan Regional Medical Center on their 50-acre campus to detailed healing gardens, small meditation courtyards, and rooftop terraces.

Laurel understands the importance of the relationship between nature and well-being. Evidence-based design is an essential part of Laurel's design philosophy and has shown that access to nature either by sight, sound, touch and/or smell lowers stress levels in users, improves healthcare delivery, and improves the image of the organization in the eyes of the community.  Laurel has authored articles on Healing Environments Master Planning & Design and Greening Affordable Housing and Rooftop Designs. She has been a guest speaker at Healthcare and Architecture Institute and Facilities Management conferences.

Through all of her project involvements, Laurel weaves a thread of leadership that creates “healthy people, healthy communities, and healthy environments”.
