HISTORY
Our firm traces its origins to June 7, 1898. On that date, George Black, Sr., who was to become a prominent Portland accountant, lawyer, arbiter and businessman in the early 1900s, began practicing law as a sole practitioner after receiving his law degree from the University of Oregon.

In 1901, Mr. Black established George Black & Co., an accounting, insurance and investment firm. In 1916, George’s oldest son, Harvey N. Black, was admitted to the Oregon Bar with a University of Oregon law degree.

After obtaining an additional law degree from Yale University, Harvey joined his father at George Black & Company in 1919 and began practicing law. Subsequently, the law practice was separated from the other businesses and continued under the name of Harvey N. Black Law Offices.
