Few projects have the potential to reshape downtown Worcester as dramatically as the conversion of the former Fallon Health headquarters into housing. Through Synergy’s acquisition of 1 Chestnut St., Greaney is spearheading what is expected to be the largest office-to-residential conversion in Massachusetts, bringing hundreds of mixed-income apartments to the city center. The project builds on his firm’s growing Worcester presence, which includes investments at 446 Main St. and efforts to attract new retail, restaurant, and events downtown.

What unique skill sets you apart from others? I’m a calculated risk-taker, and I have been since arriving in the U.S. from Ireland 30 years ago with little more than vision, discipline, and hard work.

What is one habit powerful leaders should practice every day? Invest in your relationships and keep those connections current. Leadership is a network of trust built one conversation at a time.

Why do you do business in Central Mass.? Worcester is a city with strong fundamentals, talented people, and tremendous momentum. We are proud to invest in its future.
