A member of Sheehan Phinney since 2005, Courtney represents clients in civil litigation and land use matters.

Courtney brings a practical, focused approach to litigation, working together with clients to develop effective strategies for obtaining the best possible outcome to disputes.  She regularly counsels clients in connection with the out-of-court resolution of lawsuits, both in the context of formal mediations and in informal negotiations.  She also regularly represents clients before state and federal courts, including at trial and on appeal, as well as before administrative bodies, such as the New Hampshire Commission for Human Rights, Department of Labor, and Department of Employment Security.  While Courtney handles a wide variety of civil litigation matters, she maintains a particular focus on representing employers in employment disputes and landowners in property lawsuits.

Courtney also serves as co-chair of the Land Use Practice Group at Sheehan Phinney, representing clients before Planning and Zoning Boards throughout New Hampshire in connection with seeking site plan approvals, variances, special exceptions, and more.  In that role, she regularly advises clients concerning strategies before municipal boards, and assists clients in defending or prosecuting appeals of board decisions.

Courtney served as the firm’s Director of Associate Development from 2013 through 2020, and currently serves on Sheehan Phinney’s Diversity, Equity, and Inclusion Committee.

Key Cases

  • With Sheehan Phinney partner Chris Candon, after briefing and oral argument, obtained orders from the Bankruptcy Court for the District of New Hampshire, dismissing a multi-million dollar successor liability action against a local business, and – on appeal – from the United States District Court for the District of New Hampshire, affirming the dismissal.
  • Obtained summary judgment in favor of a New Hampshire business that had been defamed by a competitor.
