NEW YORK CITY, NEW YORK / ACCESS Newswire / April 1, 2025 / With over two decades of experience in luxury real estate development and brokerage, Mark O'Brien has become a trusted leader in the industry. Mark O'Brien Real Estate and Mark O'Brien Development have been synonymous with high-end real estate since 1999, specializing in the development, sale, purchase, restoration, and renovation of premier properties across New York City, Greenwich, CT, and beyond. With the tagline "Buy, Build, Sell, Advise," the firm has successfully led over $375 million in real estate transactions, including more than $65 million invested in ground-up construction and luxury renovations.
Mark's expertise extends to modular and precast construction, historic brownstone restorations, and waterfront developments in Greenwich and New Zealand. His work has been featured in leading publications such as The Real Deal, Huffington Post, and Life and Leisure.
Mark's success story began with a personal project: a treehouse built for his five children. This 400-square-foot treehouse, perched on three trees and equipped with unique features, ultimately led to the acquisition of a waterfront property in Greenwich. Mark's ability to transform properties into dreamlike spaces was exemplified when this home sold for over a million dollars above asking price, demonstrating his skill in increasing a property's value dramatically.
Mark's approach to real estate is driven by a deep understanding of New York City's neighborhoods. With over 30 years of experience in the city, he brings unmatched insight to every transaction, uncovering hidden gems and creating real value for clients. "My family has always been my inspiration," said Mark. "My career has been shaped by the love I have for my five children, and New York City will always be my home."

Mark O'Brien Real Estate provides precise home valuations, particularly in New York's East Village, Greenwich Village, and West Village.

"Real estate is about creating value for clients," Mark explains. "Whether you're buying, selling, or understanding your home's value, we're here to offer the expertise you need."
In addition to his brokerage, Mark's development projects reflect a deep understanding of what's behind every property, allowing him to identify opportunities others may overlook-whether it's adding square footage or restoring historic elements.
Mark's brokerage, Mark O'Brien Real Estate, is a natural extension of his successful career as a developer. Leading a skilled team, Mark ensures clients understand the full potential of their properties.
