The holding company formed by the merger of Cassidy & Pinkard Colliers, Colliers Turley Martin Tucker, Colliers ABR and Colliers Pinkard named Arthur Santry as senior managing director of the national law firm practice group. The 23-year veteran will also use his leasing transaction, development and strategic planning experience as the new senior managing director of leasing for the Washington, DC, office.

Santry’s background includes three years as executive vice president of CB Richard Ellis in Washington, DC, where he was the firm’s number one producer in the Mid-Atlantic. He also served 20 years at Trammell Crow Co.

“We are thrilled to welcome a leasing professional of Art’s stature to our team,” said Joseph Stettinius Jr., president of the holding company. “His track record of providing solutions to law firms and other organizations, as well as his extensive relationships and stellar reputation for client service, will further enhance our ability to address the needs and expectations of our clients. Adding Art to our team allows us to expand our law firm leasing services throughout the country.”

Santry has completed more than $850 million in transactions in the last five years and more than 2.5 million square feet of law firm deals during his career. Some of his most notable deals include: Jones Day’s and Patton Boggs’ 350,000-square-foot leases in Washington, DC, Vinson & Elkins’ 420,000-square-foot deal in Houston, Bryan Cave’s 250,000 square feet in St. Louis, MO, Arnall Golden Gregory’s 140,000 square feet in Atlanta, and the American Psychological Association’s 600,000-square-foot lease in the District.

He has a bachelors from Hobart College and an MBA from Dartmouth College’s Amos Tuck School of Business Administration.

Cassidy & Pinkard Colliers consolidated its ownership structure with three other Colliers firms to form a single entity. Last year, the holding company completed more than $9.2 billion in global deals, including more than $3.5 billion in capital markets transactions, and managed more than 335 million square feet of real estate.
