Courtney serves on the firm’s Management Committee as the ‘At Large’ member for New Hampshire. She is an experienced trial attorney who has obtained favorable judgments for a wide range of clients. Courtney works closely with clients to implement strategies for achieving their particular goals, ranging from assisting clients in negotiating strategic settlements to litigating important issues to conclusion in court.

While Courtney represents clients in all manner of civil litigation, she maintains a particular focus on employer-side employment litigation, including those arising from claims of discrimination and retaliation, and on property-related disputes, including land use appeals, quiet title actions, and dock and water rights cases.

With Sheehan Phinney partner Megan Carrier, Courtney co-chairs the firm’s Land Use Practice Group. In that capacity, she works with clients appearing before Zoning and Planning Boards throughout the state, as well as prosecuting and defending land use decisions on appeal in Superior and Supreme Court. Among others, she has represented developers seeking approvals for a hotel, mixed use developments, a drug treatment center, and other businesses, as well as residential uses.

Courtney has practiced at Sheehan Phinney since 2005, serving as the firm’s Director of Associate Development from 2013 through 2020. She currently serves on Sheehan’s Diversity, Equity, and Inclusion Committee, and has been instrumental in the firm’s participation as a founding member of the New Hampshire 1L Diversity Internship Program.
