Firm History

J.A. Brennan Associates is a team of landscape architects and planners, committed to creating meaningful places that support both ecological sustainability and community needs. Since 1998, we’ve provided landscape architecture and planning services to public and private clients. Our work continues a tradition of thoughtful, artistic design that enhances and preserves landscapes for future generations. From neighborhood parks to regional trails, we approach each project with creativity, integrity, and a strong commitment to conservation.

We offer comprehensive services across all phases of design, including site analysis, master planning, public involvement, detail design, permitting, and construction observation. Our work includes restoring natural environments and designing vibrant urban landscapes that bring people together. We often design along shorelines and in other sensitive areas, developing site-specific solutions that protect natural systems while enhancing public access. Collaboration is central to our process, and we work closely with clients, communities, and multidisciplinary teams to create sustainable, lasting results. Our projects span the Pacific Northwest, the Western U.S., Alaska, and Asia.

J.A. Brennan is a licensed landscape architect in Guam and the Northern Mariana Islands, including Saipan, and is actively seeking opportunities to collaborate on landscape architecture projects in the region. Our work in Guam and Saipan includes resort design, streetscape improvements, parks, and open space planning. We also bring expertise in culturally sensitive design, ensuring that each project respects and reflects the unique heritage of the islands.

In addition to our downtown Seattle location, J.A. Brennan now has a satellite office in the town of Winthrop serving central Washington. This builds upon the foundation of our work in places like Chelan, Wenatchee, Leavenworth, and the Columbia and Okanogan valleys.

Designing with Nature | Recognizing the Past | Creating Environments for the Future

By designing with nature we create environments of great beauty and exceptional function. The natural features of a site provide a rich tapestry of information about how the world works including its plants, animals, land and water. Creating cultural landscapes enhance a visitor’s experience by telling the story of the place and its people. As we design for the future we emphasize stewardship of natural and cultural resources to enhance communities and the environment.

Public Involvement

Facilitating community involvement, coordinating volunteers, and incorporating user and owner input into our designs are areas in which J.A. Brennan excels.
