Colliers Brings Back an Industry Veteran

Harry Seherr-Thoss arranged the 49.9% sale of the Olympic Tower portfolio, which included iconic assets.
NEW YORK CITY—Harry Seherr-Thoss has rejoined Colliers International as an executive managing director of brokerage services. The 30-year industry veteran—who most recently served as a partner at Transwestern—previously served at Colliers in 2007, when the firm was known as GVA Williams.

In his new role, Seherr-Thoss will focus on tenant and landlord representation, strategic planning, financial analysis, and lease negotiation. Throughout his career, Seherr-Thoss has directed the successful repositioning of more than a dozen prominent Manhattan Class-A buildings, and negotiated the relocation of more than 60 international corporations, financial institutions, and law firms in New York City.

Among his notable career transactions, Seherr-Thoss arranged the 49.9% sale of the Olympic Tower portfolio that included 645 Fifth Ave., The Cartier Mansion, The Versace Townhouse, and 10 E. 52nd St., where he was the exclusive leasing agent for 20 years. He also has led agency assignments for several other important New Yok office towers including the International Plaza at 750 Lexington Ave., Tower 49 at 12 E. 49th St., 650 Madison Ave. and 712 Fifth Ave.

“With his strong track record of success and demonstration of leadership during key agency assignments, we are thrilled that Harry is re-joining our team,” says Kim Brennan, COO of Colliers' tri-state region. “His expansive market knowledge and negotiation skills will be excellent assets to our growing brokerage division.”
