From Birth to Boeing

Perkins Coie got off to a good start. Founded in 1912, the firm’s earliest clients included William E. Boeing, Sr., founder of the eponymous aeronautics company. The relationship with Boeing contributed to Perkins Coie’s reputation for representing high-tech and cutting-edge ventures in Seattle, which has become one of the nation’s technology hotspots. Today, the firm has more than 1,000 lawyers working across many industries, including aerospace and transportation, energy and natural resources, financial services and investments, life sciences and healthcare, retail and consumer products, technology, and communications.
