As Synergy continues to grow, making time to connect outside the office matters more than ever.

Our annual End of Summer Outing brought the team to Cathleen Stone Island for a day of boat cruising, team building, and some (very) friendly competition. It’s one of our favorite traditions, and a reminder that the relationships we build with each other are what make great work possible.

Thank you to everyone who joined and made the day such a success. Here’s to the people who make Synergy, Synergy! #TeamSynergy taken in Boston, Massachusetts by @synergybos

Boston has the talent. Let’s give it every reason to stay.

Together with BUILD617, we celebrated the grand opening of a new space built around that mission: a full floor in Downtown Boston where founders can work, collaborate, and build their companies… for free! It’s already home to 20+ startups building across AI, healthcare, fintech, and marketing.

Keeping our founders here takes more than encouragement. It takes action, partnership, and a community willing to open doors.

Thank you to our partners at BUILD617 and everyone who made this milestone possible. The next generation of Boston companies should have the opportunity to start here, grow here, and stay here. taken in Downtown Boston by @synergybos

What a month in Boston! Synergy and Center Plaza were all in for the Boston World Cup Group Stage matches. Located directly across from the official @fwc26boston Fan Festival in Downtown Boston, Center Plaza became a front-row seat to the energy, connection, and excitement the tournament brought to the city.

We partnered with @lifeatbgo and @artists.for.humanity to bring together nine talented teen artists to create a large-scale art installation displayed across Center Plaza’s floor-to-ceiling windows, celebrating the countries competing in Boston and reflecting the diversity and spirit of the global game.

Together with one of our tenants, @meetbostonusa , we helped create Boston House at Center Plaza — a VIP concierge experience that welcomed dignitaries, C-suite executives, and guests from around the world with a place to cool off, connect, enjoy refreshments, and watch the matches indoors. The experience was supported by Synergy alongside @newbalance , @draftkings , @thecateredaffair , @accessdmc , @telemundoni and @legalseafoods .

We also hosted a Synergy Community World Cup Watch Party in our Chrome amenity space at Center Plaza for the Portugal vs. Uzbekistan and England vs. Ghana matches, bringing together nearly 500 tenants from across our portfolio for food, drinks, music, and community.

And Center Plaza’s @thedublinerboston became one of the tournament’s most vibrant gathering spots, welcoming fans from around the world, especially the Scots.

We loved seeing the energy this tournament brought to Downtown Boston over the last month. It was a reminder of what makes Boston such a vibrant and welcoming city, and we’re proud that Synergy helped bring that experience to life. taken in Center Plaza by @synergybos

Happy St. Patrick’s Day from Synergy! ☘️

Our favorite tradition, the annual St. Patrick’s Day festivity was another huge success! We hosted nearly 1,000 employees, clients, partners, friends & family throughout the day at @bostoniapublichouse for a celebration and gesture of thanks to everyone who has helped make Synergy what it is today.

A huge thank you to the dancers from @woods.school, our band @devriboston, and bagpipes from the @bostonpolicegaeliccolumn for all their contributions, and to everyone who attending for making it such a special day.

Until next year! taken in Boston, Massachusetts by @synergybos

Synergy hosted a Broker Open House at 101 Arch Street, showcasing the building’s new Arch Street entrance, modernized lobby, and updated conferencing & amenity spaces as part of our continued investment in Downtown Boston.

The event came at an exciting time for the Downtown Boston market, where we continue to see strong momentum and growing demand from tenants. We look forward to sharing more updates on 101 Arch and other projects across our portfolio as this activity continues to build.

Thank you to our partners for their fantastic execution of this project!

As Boston's office market fights to find its footing, one investor is doubling down. Irish-born developer David Greaney has quietly spent nearly $500 million scooping up distressed office towers across the city through his firm, @SynergyBos. While many investors fled downtown, Greaney is betting that Boston's comeback will start in its overlooked Class B buildings.⁠
⁠
Greaney's strategy is simple: Find what's tired, fix what's broken and prove the market wrong. "He's been the guy," one broker said. "The only guy still buying."⁠
⁠
A onetime busboy from Limerick, Greaney has built a $2 billion portfolio on the belief that Boston's old bones still have plenty of life left. After sitting out the late 2010s, he's back in full buy mode — turning the city's office slump into his next opportunity.⁠

Members of the Synergy team sponsored & participated in the 2025 Boston Inclusive Cornhole Tournament benefiting Special Olympics Massachusetts. We had the opportunity to team up with Special Olympics athletes for an afternoon of competition, community impact, and fun.

Beyond the games, it was a meaningful reminder of why these events matter: bringing people together around a cause that creates real change. A big thank you to Special Olympics MA and Dan Collins for the incredible work you do!

Synergy’s CEO, David Greaney, joins “Good Dirt Podcast - Conversations with Leaders in Real Estate and Beyond” for what the hosts, Mike and Tom Greely, call “a rare, behind-the-curtain look at Synergy.”

From arriving in the US on a summer work visa to building one of Boston’s largest commercial real estate portfolios – nearly 7 million square feet across 30+ assets – David Greaney shares the complete story. He opens up about his early investing lessons, the serendipitous moments that shaped his path, and the strategic vision behind transformative acquisitions like 99 High Street and 1 Liberty Square.

This isn’t just another success story – it’s insights from someone actively shaping Boston’s economy while working with Governor Healey’s administration on the state’s housing crisis. A “must-listen” for understanding how visionary leadership transforms cities.

With summer officially coming to a close, there’s no better way to mark the transition than gathering with the team and @bostoniapublichouse at the @synergybos HQ, 10 Post Office Square.

Pool games, excellent food, fresh oysters, and great conversations with colleagues – the perfect send-off to the season as we head into fall together!
