Firm Notes

Landscape architects Hideo Sasaki, (1919-2000), and Peter J. Walker, (born 1932), formed their partnership in 1957. Ttheir first office was located in Watertown, MA. Walker, along with Anthony Guzzardo, opened a second one in San Francisco, CA, in 1959, to supervise the landscape planning of Foothill Junior College, Los Altos, CA (1962). The San Francisco office remained affiliated with the Watertown firm until 1974. (Sasaki, however, removed Peter Walker's name from the Watertown office in 1966 [it became known as "Sasaki Dawson, DeMay and Associates"], a source of some friction between the two partners.) In later years, this office shortened its name simply to "Sasaki."

Hideo Sasaki practiced with his part of the firm until his retirement in 1980.

Peter Walker moved permanently to San Francisco, CA, in 1975 and left Sasaki Walker Associates in 1983, in order to operate his own, smaller firm, Peter Walker and Martha Schwartz. Sasaki Walker Associates rebranded itself as the "SWA Group" after Walker's severance with the firm, c. 1984.

In 2005, the SWA Group operated offices in Sausalito, CA, San Francisco, CA, Laguna Beach, CA, Houston, TX, Dallas, TX, and Shanghai, China.

The firm has had a number of long-time institutional affliliations on the West Coast; one of these was with Stanford University, for whom SWA performed over 300 projects during a 25-year span.

On 12/01/2016, Some principals involved in SWA's New York operations merged with Thomas Balsley Associates to form "SWA/Balsley."

In 2020, the SWA Group maintained eight offices in the United States and China. They included its main headquarters in Sausalito, CA, (2200 Bridgeway Sausalito, CA 94965), Laguna Beach, CA, (570 Glenneyre Street, Laguna Beach, California 92651), Los Angeles, CA, (811 West 7th Street, Los Angeles, California 90017), San Francisco, CA, (530 Bush Street, 6th Floor San Francisco, California 94108), Dallas, TX, (2001 Irving Boulevard Dallas, Texas 75207), Houston, TX, (712 Main Street, 6th Floor Houston, TX 77002), Shanghai, China, (718 Building 1, Jiashan Road Loft No. 508, Floor 7 Shanghai, Xuhui District 200031), and New York, NY, (31 West 27th Street, New York, NY).
