SIOR Global CEO Robert Thornburgh to Step Down at Year’s End
The Society of Industrial and Office Realtors (SIOR Global) announced that Robert Thornburgh, SIOR, will conclude his service as CEO of the organization at the end of 2024. Having fulfilled an opportunity to make a lasting impact on the next chapter of SIOR, Thornburgh is positioned to take on the next leadership role in his commercial real estate career.
Thornburgh will assist through a transition period. SIOR Global’s governance committee will conduct a search for a new CEO to lead the global organization that’s grown to more than 4,000 members in 50 countries.
Twenty-five-year industry veteran Thornburgh, the Board of Directors and other dedicated leaders have guided SIOR Global through the most dynamic period of its 83-year history. The groups’ transformative vision led to the implementation of SIOR’s new strategic plan, which has produced a record-breaking 97% membership retention, increased member satisfaction and earned top CRE brand recognition by Lipsey two years in a row. SIOR has also seen 18% membership growth over the past three years, a 27% increase in female members, a 19% increase in international membership and the attraction of younger professionals to the organization.
SIOR President David Lockwood, SIOR, said, “Robert’s perseverance and dedication to a forward-thinking vision has created new levels of excitement, energy, and opportunity that SIOR is realizing today. His collaborative approach, committed leadership and inspirational enthusiasm served as critical elements toward establishing a new, dynamic organization that has been built on top of a storied foundation.”
Thornburgh said, “Serving SIOR has been the privilege of a lifetime. I am incredibly grateful for the trust and support of the Board of Directors and SIOR Global team, as well as our dedicated members around the world. I am so proud of what we have accomplished. Together, we have elevated the SIOR brand, enhanced our member services, and cultivated a dynamic, collaborative community that continues to raise the standard of excellence.”
