ABOUT TCN
One of the Industry's Most Powerful Commercial Real Estate Networks
Founded in 1989, TCN Worldwide is a consortium of independent commercial real estate firms delivering integrated real estate solutions locally and internationally. With more than 70 offices, operations in 24 countries, and professionals serving over 200 markets, TCN is positioned among the largest service providers in the commercial real estate sector.
The network handles roughly $47.3 billion in annual transactions and manages over 190 million square feet of space — a scale that provides member firms with data, relationships, and capabilities that would be impossible to develop independently.
Unlike large national brands, TCN is built on the strength of locally-expert, independently-owned firms. Each member is selected for its market leadership, professional standards, and commitment to client service — ensuring that the same quality Landmark delivers in Central Pennsylvania is replicated in every market across the network.
“A global network of independent commercial real estate firms delivering integrated solutions with corporate accountability and entrepreneurial commitment.”
