Fifth Madison Group is an elite team of hands-on real estate advisors operating on the Upper East Side at Brown Harris Stevens, Manhattan's preeminent and oldest residential brokerage. With over a decade of experience navigating the neighborhood's most exclusive cooperatives, condominiums, and townhouses, we offer a level of service defined by thoughtful planning, strategic negotiation and industry leading creative marketing, which allows our clients to consistently outperform the market, regardless of broader market conditions.
It is our sincere belief that our role as advisors is to advertise our clients' property, not to advertise ourselves. We do not collect listings, and we only become involved in projects where we know that we can achieve the best possible outcome - often quickly - and our systems are continuously refined with that outcome in mind.
Fifth Madison Group was founded by Justin Duffy and Mikael Johansson.
