DALLIEN is a vertically integrated real estate brokerage headquartered on Fifth Avenue in Manhattan. Founded by brothers Greg and Graham Jones who have backgrounds as brokers, investors, and developers, DALLIEN brings a developer’s mindset to every transaction—treating real estate not as transactional, but transformational.
Whether working with buyers, owners, or developers, our approach is always bespoke—built on precision, intention, and value.
Every owner has a vision. Every property holds potential. We don’t hand over cookie-cutter plans—we co-author bespoke business strategies built around your building’s DNA.
You don’t need another leasing agent. You need a partner who understands capital, compliance, and cash flow.
