Practice groupLitigation, Arbitration, and Employment

Haley Costello Essig understands and has experience in all stages of litigation and arbitration, and she's prepared to guide clients from a wide variety of industries and backgrounds through these complex processes. But she also believes there's great value in working with clients before litigation needs arise; she has often worked with clients to try to mitigate their industry-specific litigation risks.

Based in our Northern Virginia office, Haley has worked in both domestic and international litigation and arbitration, representing energy, financial, real estate, government, manufacturing, service, and nonprofit entities. Prior to joining Hogan Lovells, she was an associate at a large U.S.-based firm.

With roots spanning the length of the east coast, Haley called the University of North Carolina School of Law "home" for three years. There, she was an articles editor for the North Carolina Law Review and a member of the Broun National Trial Team. She also had the opportunity to represent clients in juvenile court through her participation in the Juvenile Justice Clinic, and was recognized for outstanding appellate oral advocacy with the Gressman-Pollitt award.

After law school, Haley had the distinct honor of serving as a law clerk to Justice Cheri L. Beasley of the Supreme Court of North Carolina.
