Verified record
Brian Gagnon is a solo-practice Realtor® with Coldwell Banker who works Boston, Milton, and Dorchester; his Massachusetts real estate broker registration is verified active. The company's own site says he was drawn to the business early, following his father's decades-long career, and cites over 20 years of his own experience — the site's own account, not something independently verified. The written record — 33 reviews stretching from 2021 to a current Google 5★ average from 48 ratings — keeps circling back to results, not just niceness. In a 2021 review, one seller says Brian negotiated $60k over asking and sold the first weekend; a 2023 review describes a Dorchester condo that sold above list price within a week, timed to the market; another 2021 account credits him with a record sale price for a Milton multi-family. A 2022 review lays out the legwork behind a South End sale in detail — Brian personally organizing cleaners, a painting contractor, professional photography, virtual staging, and the pre-closing smoke inspection. The relationships run long, too: a 2023 review from a Beacon Hill seller says Brian first reached out three years earlier about a neighboring sale, checked in periodically without pressure, and was still the one they called when they were finally ready to list. Nothing negative shows up anywhere in the written record, across five years and three sources — an unusually clean run for this much volume. The two most recent reviews, from March 2026, describe the same pattern still holding: a smoother-than-expected Milton sale and a mortgage lender's account of a proactive, well-communicated closing. The site also states he's been recognized as a top-1% Coldwell Banker agent worldwide and has received nine consecutive International President's Premier Awards — brokerage-issued distinctions, not independent verification, but consistent with the volume above. For a Boston-area sale or purchase, especially in Milton or Dorchester where several reviewers specifically cite his market knowledge, this is a licensed agent with a long, well-documented track record and nothing on the record to weigh against it.
If you’re selling a house in Milton or anywhere in the Greater Boston area, do yourself a favor and call Brian Gagnon first. We worked with him to sell our home in Milton, MA, and the whole process was smoother than we expected — and that’s saying something because real estate is usually anything but smooth.He knows the local market inside and out, gives honest advice (even when it’s not what you want to hear), and somehow keeps everything moving without making you feel rushed. At one point we ran into an issue during the process, and he handled it calmly and helped us work through it without any drama — exactly what you want in a real estate agent. Brian Gagnon is professional, responsive, and always available no matter where he was or what time it was, which made the whole experience a lot less stressful than we expected.Bottom line: Brian is an. excellent real estate agent, great to work with, and we’d use him again in a second. Highly recommend if you’re buying or selling in Milton or anywhere in the Greater Boston area. Michael & Arleen Bernardi
As a mortgage lender, I had the pleasure of working with Brian on a recent transaction and was very impressed with his professionalism and communication. He was very proactive, responsive, and kept all parties well-informed throughout the process, which helped ensure a smooth and timely closing. I look forward to working with Brian again in the future and would gladly recommend him to anyone looking for a knowledgeable and reliable real estate professional. -bc
My husband and I found Brian through Instagram, knowing that our main pick of a town was Milton. Brian was extremely knowledgeable about the area, advised on where we would/would not want to be with our growing family and young children, and ultimately helped us find the perfect home. We knew Milton was a competitive market so having someone who knew the area, comps, the kind of offer we should make was invaluable. I truly believe we would not have gotten the home we did if not for Brian. And he continues to be a great contact for us to meet new people, find new spots, and connect us with contractors. I highly recommend working with Brian if you’re looking for your dream home!
We hired Brian Gagnon based on his proven track record, marketing expertise, and the incredible results he gets — including an Instagram video he created for our listing that received over 20,000 views! Brian listed our South Boston condo in a market where many places were just sitting, yet his precise pricing strategyand thoughtful marketing plan generated multiple offers — and we ended up with an offer that blew our socks off. The key with Brian is that he truly “walks the walk.” He’s not just saying what works in real estate — he’s doing it every day. A likable guy with a calm, attentive manner, Brian never strays from the goal and always takes the time to listen. I learned a lot just watching his natural, intense focus in action. And beyond being a great agent, he’s also a hockey dad— which says a lot about his patience, teamwork, and drive. Highly recommend! 🏡🏒
Brian went above and beyond to help me find my dream home He is so patient honest and truly cares about his clients -I couldn't have asked for a better experience Highly recommend
