After graduating in Engineering from the University of Ulster, Northern Ireland, David Costelloe came to New York in ’94 and has lived here since. More than half of those years have been spent at Halstead Real Estate dedicating himself to becoming one of their most trusted and successful agents.

With calmness and absolute commitment he has helped guide clients through the intricate process of buying, selling, and leasing co-ops or condos with thorough market research, clear and responsive communication, and a determination that conveys the utmost confidence.

A natural conversationalist, David has the ability to connect with all those involved in the transaction. Using his inventiveness and capacity to problem solve he can cut through the noise and navigate the deal to the closing table. His ability to be clear and concise allows him to set expectations and a high-definition road map of the transaction.

David has enjoyed a successful partnership with Jane Greenberg since 2008 and together they have closed dozens of sales in Manhattan and Brooklyn where they have excelled by implementing tailored pricing and marketing strategies for each property.

An avid rugby player in college, David continues to keep fit and focused, running and biking through the city as he trains to compete in another triathlon or marathon.
