Years rooted in Muttontown
Brian Fagen, Esq. is a Licensed Associate Real Estate Broker at Compass and a currently registered New York attorney. He grew up on, and now raises his family on, Long Island — and he has spent his entire professional life inside the systems that make a transaction succeed or unravel: the courtroom, the boardroom, and the building department.
Brian earned his B.A. from Indiana University and his J.D. from St. John's University School of Law before being admitted to the New York State Bar in 2003. He began his career as an Assistant District Attorney in the Kings County (Brooklyn) District Attorney's Office, then served as Executive Vice President of Prestige Toy Corp, leading corporate operations and high-stakes negotiations. Today he carries that same discipline into every contract, inspection, and closing.
He joined Compass after a tenure at Douglas Elliman's Syosset office, and his transactions stretch from $10M lofts in TriBeCa and Upper East Side co-ops to Gold Coast estates in Mill Neck, Cold Spring Harbor, Muttontown, and Laurel Hollow, plus oceanfront homes on Dune Road in Westhampton. Long Island Business News has named him in more than a dozen "Priciest Sales" features across Glen Cove, Huntington Bay, Oyster Bay Cove, Syosset, Cold Spring Harbor, and Brookville.
Specialties
The builder's eye
Construction fluency isn't a tagline for Brian — it's how he walks a property. As Village Trustee in Muttontown he campaigned on overhauling a broken permit and certificate-of-occupancy process, and he sits across the table from building departments, surveyors, architects, and contractors on a regular basis.
That means when you're considering a home, he can flag the open permit, the unpermitted addition, the failing oil tank, the wetlands setback, the roof-line that won't survive a renovation budget — before you're emotionally committed. And when you're selling, he knows exactly which fixes move price and which ones just spend money.

Civic & community
Elected to the Village Board in 2018 on a reform slate focused on streamlining building permits and certificates of occupancy — work that gives him daily, firsthand insight into how Long Island municipalities actually approve, value, and tax homes.
A lifelong patient advocate, Brian chaired the chapter's 2019 Annual Gala for a Cure, raising $400,000, and is a certified IBD support-group facilitator. "As a real estate agent I have the unique opportunity to get to know my clients and find out what's important to them."
Brian lives in Muttontown with his wife, Randi, and their two children — the same community he has called home for more than a decade and where many of his sales originate.
"Brian was extremely helpful and professional. We had a limited time frame to see houses, and Brian showed us houses for an entire weekend. He was also successful in getting our offer accepted on a house that had many competitive offers. We highly recommend him."
Buyer Client

"Brian knows the Long Island market better than any broker I know, from west to the east end. In addition, his legal background adds incredible value throughout the process. He's honest and straightforward, and stands out from the rest. Highly Recommend!!"
Repeat Client
Long Island, NY
"Brian is nothing short of stellar! He helped my husband and I on both sides — to sell our home and purchase a new one. He is knowledgeable, friendly, and honest and treated us like a friend throughout the entire process. He was always reachable (even on vacation!) and beyond patient answering questions and walking us through every step of the way. We would highly recommend Brian to anyone!"
Buyer & Seller
Long Island, NY
"Brian did a fantastic job helping me find a beautiful house in East Northport. It was clear that Brian had a lot of knowledge about homes in the area. Brian was kind, informative, responsive, and determined. He made me feel at ease knowing we were always moving in the right direction to close the house. I would highly recommend Brian Fagen for anyone who is looking for a house on Long Island."
First-Time Buyer
East Northport, NY
"Brian was amazing. So helpful in the process and was just as eager as myself and my fiancée. We would be texting him late into the night about homes and then going to see homes at night. It took a while but we found something we all fell in love with. Love Brian a lot and he has become a friend as well."
