The Society was established in 1941, when the Federal Government asked a group of brokers to help them locate industrial facilities around the country that were needed to support the war effort. This group became known as (SIR), which stood for the Society of Industrial Realtors. Over the years the membership was expanded to included office brokers as well, and the name evolved into what is now SIOR, the Society of Industrial and Office Realtors.
Today, the Society has become the leading professional commercial and industrial real estate association with more than 3,200 members in more than 590 cities in 25 countries. SIOR represents today’s most knowledgeable, experienced, and successful commercial real estate brokerage specialists.
