One of our most requested guests, David Greaney is the Chief Executive Officer of Synergy, a Boston-based real estate investment and management company that he founded in 2003. Synergy owns and operates over 30 commercial assets in the Greater Boston area, totaling nearly 7 million square feet. Over 500 companies, retailers, and organizations occupy space in the Synergy-owned portfolio.

Greaney has played a pivotal role in shaping Boston’s economy and downtown landscape, recently leading transformative acquisitions such as 99 High Street, 101 Arch Street, and 1 Liberty Square. His vision for integrating investment, asset management, leasing, construction, property management, accounting, and hospitality has positioned Synergy as a leader in delivering tenant-focused, amenity-driven spaces that consistently outperform market benchmarks.

Beyond commercial real estate, Greaney is deeply invested in Boston’s hospitality scene, with ownership in over a dozen restaurants that bring vibrancy, foot traffic, and jobs to the city’s core. He also works closely with Governor Healey’s Administration to address Massachusetts’ housing crisis, focusing on adaptive reuse opportunities.

Active in civic and industry leadership, Greaney serves on the boards of NAIOP Massachusetts and the Downtown Boston Alliance. Since relocating from Ireland in 1995, he has raised millions for philanthropic causes on both sides of the Atlantic, including Bridge Over Troubled Waters and The Ireland Funds. Greaney has received many accolades for his leadership in Boston, including being recognized for two consecutive years in the Boston Business Journal’s “Power50: Movement Makers” list, and Synergy has received the Commercial Broker’s Association “Landlord of the Year” Award.

Greaney is a graduate of the University College Dublin. Prior to founding Synergy, he worked at Harvard Management Company and PricewaterhouseCoopers. Greaney resides on the South Shore of Massachusetts with his wife and seven children. In his free time, he enjoys traveling and playing golf.
