Sean O’Brien
Broker | Appraiser | New Hampshire Real Estate Specialist
Born and raised in Northfield, NH, Sean brings deep local knowledge and a practical, no-nonsense approach to every transaction. With a broker’s license and a New Hampshire appraiser’s license, he offers clients a rare combination of sales expertise and accurate valuation insight.
Before entering real estate, Sean spent more than 15 years in the golf course industry, where he developed a sharp eye for detail, a strong work ethic, and the ability to manage complex projects. He has carried those same standards into real estate, where he has helped buyers and sellers since 2017 across residential, multi-family, commercial, land, new construction, and foreclosure properties.
As an associate broker and certified drone pilot, Sean regularly provides high-quality aerial imagery that gives clients a clearer understanding of a property and its surroundings. He is equally comfortable guiding first-time homebuyers, negotiating investment deals, or navigating zoning and development questions.
Clients consistently describe Sean as honest, responsive, and thorough, someone who treats every deal like it matters because, to him, it does. Whether you’re buying your first home, selling a commercial building, or evaluating land for a new project, Sean is ready to put his local knowledge, dual licenses, and hands-on experience to work for you.
