Donal O’Sullivan/Navillus Contracting


A native of Ballinskelligs, Co. Kerry, Donal O’Sullivan immigrated to the United States in 1984 in search of work in construction. Today, he is the president and co-owner of Navillus Contracting, which he founded with his sister Helen, and his brothers Kevin and Leonard. Navillus, one of the largest union contractors in New York City, has been contributing to the city skyline for the last 24 years. Most notably, it was Donal’s great privilege and honor to have Navillus involved with the building of the 9/11 Memorial at the World Trade Center.

Donal is a supporter of the Irish Arts Center and the GAA. He is a member of the Kerryman’s Patriotic & Benevolent Association and the Kerry Football Club of New York, which named him Guest of Honor in 2010. He serves on the Board of Haven U.S., an extension of the Haven Partnership, an Irish nonprofit organization dedicated to creating opportunity and building homes for the people of Haiti. Donal and his wife, Kathleen, have six children, Jack, Donal, Katie, Caroline, Michael and Kelly. He frequently travels back to Ireland to visit his mother, Teresa, as well as other family members, and to connect with his Irish roots.
