The new company, which will be a conglomerate of a number of smaller firms, will be headquartered here. It will officially open for business March 1, 2010. CTMT's current chief executive Mark Burkhart will take on the role of CEO and will remain in St. Louis. Chairman Wally Pinkard will work out of Baltimore. Joe Stettinius, CEO of Cassidy & Pinkard Colliers in DC, will be president.

The new move is in the best interests of the companies' clients and employees, Stettinius tells GlobeSt.com in another article. "We are not doing this to save money or be more efficient – we are doing this to grow our pipeline and revenue."

Cassidy Turley will combine Colliers Turley Martin Tucker, Cassidy & Pinkard Colliers, Colliers ABR, Colliers Pinkard, BT Commercial, BRE Commercial in Southern California and BRE Commercial in Arizona.

In August 2008, Colliers Turley Martin Tucker, Cassidy & Pinkard Colliers, Colliers ABR and Colliers Pinkard consolidated its ownership to form a holding company. That year the company conducted $9.2 billion in global transactions. Now the previously NAI affiliated BT Commercial, located in Northern California, and the Grubb & Ellis affiliated BRE Commercial in Southern California and BRE Commercial in Arizona, will join the group.

Cassidy Turley's portfolio will include 420 million square feet of managed space. It will employ 2,700 people in 57 locations. The move makes Cassidy Turley the fourth largest commercial brokerage company in the US, behind CB Richard Ellis and Jones Lang LaSalle, according to 2008 revenue figures.
