Sebastian is consistently placed among the Corcoran Group's top 25 Manhattan brokers. In 2024, RealTrends Verified ranked him among the top 10 broker in Manhattan, top 15 in New York State and top 100 broker in the USA for individual new development sales.

Sebastian moved to New York City to join the Corcoran Group as Global Sales Director of Corcoran Sunshine in 2016. Expertly navigating the complex and competitive New York market, he makes it his mission to deliver the highest long-term value for his clients.

As part of Corcoran Sunshine, Sebastian headed up the successful global sales launch of the first residential tower at Hudson Yards, one of the largest private real estate developments in US history, and 53West53 above MoMA, one of Manhattan’s most sought-after addresses.

In 2021, Sebastian represented 67 Vestry Street, the former home / gallery space of Andy Warhol, John Chamberlain, Mark di Suvero and the Dia Art Foundation. With sales spearheaded by Corcoran Sunshine, the building became one of Downtown’s largest sales successes after selling out within only eleven months while being promoted predominately off-market.

On the hospitality management side, he worked together with Aman Resorts, Mandarin Oriental Hotels, the Ritz-Carlton Group and the Greenbrier Hotel Group.

Having been involved in over $1.2 billion of real estate transactions, Sebastian is an invaluable asset in navigating the intricate dynamics of New York City’s ever-changing real estate market.
