55+ YEARS OF EXCELLENCE

From Leisure World to Rossmoor Walnut Creek


 
Since 1964, Rossmoor has evolved from a visionary concept into one of the nation’s premier active adult communities. What began as Ross Cortese’s ambitious dream has grown into a thriving independent senior living community offering an exceptional lifestyle in the heart of the Bay Area.

A Dream Realized in 1960


Rossmoor began with an innovative dream: to create a country club atmosphere with a price tag that middle-class seniors could afford. Developer Ross Cortese purchased the 2,200-acre estate belonging to the prestigious Dollar family, founders of the Dollar Steamship Lines.
 
Cortese saw beyond the family’s summer home and pastoral land. He envisioned a place where active adults could write their next chapters surrounded by natural beauty, modern amenities, and a low-maintenance lifestyle.

 

Groundbreaking Approval in 1963


In a landmark decision, the Walnut Creek City Council rezoned the property for senior housing development, establishing the community as one of the nation’s first master-planned active adult communities.

Our Journey Began in 1964


Construction for the homes and first clubhouse began reshaping the landscape of Tice Valley in 1964 for what was then called Rossmoor Leisure World of Walnut Creek. The first 3,300 manors built were all cooperatives.
