Buyer Relationships &
Property Marketing

Luxury Real Estate Advisor · SERHANT.

Lindsey leads buyer relationships and property marketing, bringing hands-on experience working with buyers and sellers on a top-performing Boston luxury real estate team. Her work spans understanding a buyer’s priorities, preparing homes for market, shaping property presentation and helping clients navigate a purchase or sale.

She also helped drive major new-development communities in the Seaport, South End and Cambridge with Berkshire, Greystar and National Development. A Seaport resident, she combines that building-side experience with a practical understanding of how to present a home’s strongest qualities and help buyers weigh the choices in front of them.

In the South End, that means weighing the character of a brownstone or garden duplex alongside the services and shared spaces of a newer building. The right choice begins with the daily routine you want.

Luxury Real Estate Advisor · SERHANT.

Derek brings deep experience in Boston’s high-end luxury real estate market. Before partnering with Lindsey, he served as Chief of Staff and Director of Market Analysis and Operations for a leading Boston luxury real estate team, helping coordinate the strategy and execution behind complex listings and acquisitions.

His work spans market analysis, positioning and repositioning strategy, marketing execution, client communication, transaction systems, paperwork and compliance. For buyers and owners, that experience connects the pricing decision to the negotiation, the marketing plan and the work needed to close.

His Marine Engineering degree from Maine Maritime Academy and MBA from Boston College reinforce the method: define the variables, test the assumptions, manage risk and execute.

For a South End search or sale, he brings that discipline to the differences between a square-front townhouse, a multilevel brownstone condominium and a contemporary amenity building.
