About
Massachusetts REALTOR® with Lamacchia Realty, serving Greater Boston and Nantucket.
The Agent
Bill McGowan is a REALTOR®, ABR and e-PRO with Lamacchia Realty's Waltham office, with a real estate career beginning in 2002 and a niche practice on Nantucket alongside his Greater Boston business.
Bill built his real estate practice on an unusual foundation: he struck out on his own at 18, traveled extensively for four years, then lived in Upstate New York, Nantucket Island, towns across Cape Cod and Palm Beach before returning to finish his education at Cape Cod Community College, Assumption College, Harvard University and Northeastern University.
That broad life experience carried directly into his real estate work. Bill has built a specialty representing Nantucket sellers and buyers as what he calls the island's off-island agent alternative, alongside his core Greater Boston practice out of Lamacchia Realty's Waltham office.
Once you reach out, here's what to expect: a straightforward conversation about your goals, matched with an agent who brings real energy, marketing skill and internet proficiency to buying or selling your home.

My wife and I were concerned that in this difficult sellers' market, we would have a lot of difficulty finding a home to purchase. Yes, things were difficult, but we prevailed by finding a great condo with ample space for visitors. Many thanks to our Lamacchia Realty agent Bill McGowan for his determination and hard work.
