Why Hire an SIOR



The World's Best All In One Place

A Network of Industry Leaders

For more than 80 years, the world's elite CRE brokers have belonged to a premier professional organization known for integrity, ethics, and success: the Society of Industrial and Office Realtors.

The professionals who carry our name aren't just successful brokers, but partners, thought-leaders, and mentors, all required to adhere to the industry's highest production and ethical standards. You can take advantage of a worldwide network of 3,900 members in over 50 countries, confident that each designee has been carefully vetted to meet our unmatched standards for excellence and honesty.


Working with an SIOR is about gaining access to market knowledge, industry expertise, reliability, and honest and deliberate insight, solely focused on the wellbeing of your business. With an SIOR, you get:
  • Access to a Global Network - You can adapt every new opportunity with the support of thousands of SIOR global members, each of whom can deliver guidance when you need it most.
  • Knowledge and Expertise - From a sudden crisis to emerging opportunities, SIOR members aren't just brokers, they're part of your team and always at your disposal.
  • A True Partnership - Being successful also means exceptional vision into the industry and individual markets, with the experience to stay a step ahead of the competition.
  • A Network of Closers - It's not just the billions in transactions SIORs produce that makes them special. It's because when the future of your business is at stake they get the job done.


One can’t just become [an SIOR] overnight. So, when you decide to work with an SIOR broker, you know you’re talking to somebody who has already been through that process and through the gauntlet of what it takes to become the best. And you know you’re getting that level out of the gate.
