Landscape Architecture

Founded in 1899, ASLA is the national professional association for landscape architects, representing more than 15,000 members in 49 professional chapters and 72 student chapters. Members of the Society use the “ASLA” suffix after their names to denote membership and their commitment to the highest ethical standards of the profession.

ASLA's Oregon Chapter is the state organization for landscape architecture professionals. With over 300 members statewide, the chapter provides events, training, and advocacy for a range of topics that affect the profession throughout the state.

Through research, technology, and education, the International Society of Arboriculture (ISA) promotes the professional practice of arboriculture and fosters a greater worldwide awareness of the benefits of trees.
