Secretary
Isabella Jimenez, ASLA, SITES AP
Associate, Moody Graham

The Potomac Chapter region is where Isabella first developed a foundation in landscape – both as a discipline and a lived experience. Some of her earliest memories include picnicking on the National Mall, biking the steep hills of Rock Creek Park, and celebrating holidays with family along the Old Town Alexandria waterfront. Growing up in and around Washington, D.C. was a profoundly formative experience, shaping not only her sense of design but also instilling a strong sense of civic responsibility and a deep appreciation for the power of place. Grateful to have been raised in this cultural hub and iconic city, Isabella seeks to honor that upbringing by using the skills gained through practice and study to serve the region’s diverse, resilient communities and environments.

Formally trained at the University of California, Davis—in a landscape markedly different from her home, Isabella has since worked on a broad range of project types, both locally and internationally. This diverse exposure has provided her with a wide-angled understanding of the built and natural environments and fuels her ongoing pursuit of translating space into place. She is committed to approaching each design with a focus on authenticity, integrity, and the intention of leaving every landscape imbued with purpose, beginning with her own garden, which she tends to with joy.
