TIA Welcomes New Interim CEO

Doug Clark, Established Industry Executive & TIA Honorary Life Member, to Lead TIA During Executive Search


JUNE 12, 2020 – ALEXANDRIA, VIRGINIA – Transportation Intermediaries Association (TIA), the voice of the third-party logistics industry, announced today that Douglas G. Clark has been named Interim CEO of TIA, effective June 10, 2020.

Clark joins TIA with more than 40-years’ experience in the transportation and logistics industry, having started his career in 1979 at produce brokerage firm Golman-Hayden, where he would end up serving as Executive Vice President. He would later go on to become President of Greatwide Freight Brokerage Division following the acquisition of Cargo-Master by Greatwide Logistics Services in 2005.

“I have worked alongside Doug for more than 15 years and I am more than confident that he is prepared and equipped to serve as Interim CEO of the association,” said Brian Evans, TIA Board Chair and CEO of L&L Freight Services. “His extensive industry knowledge and commitment to TIA over the past several years puts him in the perfect position to lead the association while our Board of Directors conducts an extensive search for the next President & CEO of TIA.”

Clark succeeds Robert A. Voltmann, CAE, who announced earlier this week that he was stepping down from his role in leading the association after nearly 23 years.

“As the current Chair of TIA’s Legacy Committee and former Chair of TIA’s Board of Directors, I have experienced and contributed to the good work that TIA has done over the years to establish a voice for our members in Washington and around the world,” said Doug Clark, Interim CEO of TIA. “As Interim CEO, I am committed to continuing to support policies and strategies that expand our relationships, educate our members, and most importantly support, the 3PL industry as a whole.”


As Executive Vice President at Golman-Hayden and President at Cargo-Master, Clark was responsible for supervising the operations of 26 transportation brokerage offices nationwide. He also was responsible for managing revenues in excess of $160 million and helped to oversee all daily operations.

Clark resigned from Greatwide in 2009 and following the expiration of his non-compete in 2012, was named Vice-President of Business Development for the Allen Lund Company. He served in this position until 2016, when he entered the transportation consulting sector, working with many of North America’s leading brokerage companies.

Clark currently serves as the Chair of TIA’s Legacy Committee and previously held the positions of TIA Services Chair (2015-2018), Executive Committee Member (2003-2013 & 2015-2018), Education & Program Committee Chair (2011-2020), and TIA Board of Directors Chair (2007-2009). He was also presented with TIA’s Heritage Award in 2011 and is an Honorary Life Member of TIA.

Clark now proudly serves as the Interim CEO of TIA, while the Board continues their search for a permanent replacement.
