About 
DALLIEN

DALLIEN is a vertically integrated real estate brokerage headquartered on Fifth Avenue in Manhattan. Founded by Greg and Graham Jones, long-time New York residents originally from Short Hills, New Jersey with backgrounds as brokers, investors, and developers, DALLIEN brings a developer’s mindset to every transaction—treating real estate not as transactional, but transformational.

​

Our portfolio spans thousands of apartments across Manhattan and Brooklyn’s most coveted locations, with expertise that includes advising on 276 buildings, 3,427 renovated units, and multiple hotel repositionings across four boroughs. Whether working with buyers, owners, or developers, our approach is always bespoke—built on precision, intention, and value.

What sets us apart is trust. Our clients entrust us with their most personal spaces, and we honor that by protecting discretion at every stage. Unlike traditional brokerages, we intentionally refrain from publishing listings online—because in today’s world, privacy is the last true luxury.

​

Our agents partner with buyers, owners, and developers to craft tailored marketing and pricing strategies—consistently achieving record results and setting new benchmarks for our neighborhoods. With in-house marketing that rivals luxury lifestyle brands and a culture that values coaching as much as closing, DALLIEN represents more than property—we represent vision.

​

The future of New York real estate belongs to those who build it.

At DALLIEN, we build with intention.
