Professional Experience

John P. Maher is an Executive Vice President of CBRE and an exceptionally dedicated member of the organization, having begun his career with the firm as the inaugural participant in CBRE’s highly regarded “Wheel” program. His strong tenant-side focus has led to the leasing of more than five million square feet of space with an aggregate value of close to $4 billion. On the agency side, he currently represents Boston Properties’ world-renowned GM Building. He also represents 1271 Avenue of the Americas, the former Time Life Building, owned by Rockefeller Group, a wholly owned subsidiary of Mitsubishi Estate; this two-million-square-foot asset is currently undergoing an extensive $300 million renovation and repositioning led by celebrated architecture firm Pei Cobb Freed & Partners. In addition, John has been the leasing agent for Class A properties owned by Hines Interests, Jaymont Properties and CBRE Investors. 

One of CBRE’s leading leasing consultants, John is valued for his consistency, broad range of skills, creative problem-solving abilities and client focus. A member of the Colbert Coldwell Circle (the top 3% of all producers nationwide) and the Chairman’s Club (the top 100 professionals worldwide) numerous times, John has been CBRE’s number one New York City leasing broker three times. 

John’s clients have taken him all over the world—besides most major U.S. cities, he has negotiated transactions for clients in London, Paris, Tokyo, Beijing, Buenos Aires, Geneva, San Juan and San José. He uses the relationships he has developed in his 28 years at CBRE to work with the best professionals in each market, keeping his clients in sure hands—and ensuring they reap the benefits of CBRE’s standing as the world’s number one commercial real estate services firm.

Frequently quoted in major publications, John has been published in the New York Law Journal, appeared as a guest on various television news programs and lectured for the New York State Bar Association.
