President & Owner
Ambitious, hardworking, loyal, and generous are just a few of the words used to describe Donal by those who work with him. Donal started Navillus with his sister, Helen and brothers Kevin and Leonard over 30 years ago and Donal has never stopped driving the business forward and growing it into what is now the largest union contractor in all of New York City.
Originally from Ballingskellings, Ireland, a small village of less than a few hundred people in the southern part of County Kerry, Donal understands what it takes to build lasting relationships and grow a reputation by achieving notable results. Fast turnaround, high quality and loyalty are what Donal is known for along with his constant push to innovate. Donal is an optimist who believes in the capability of human ambition to overcome challenges and generate success through adapting and innovating with the changing times. His personal story reflects this – emigrating from Ireland when jobs were scarce, and setting out with his own business when he saw a niche in the industry.
Donal never forgets where he came from, and as a result he always gives back and supports a variety of Organizations, associations and programs at local level from habitat for humanity projects to cultural & heritage development to annual fund-raising charity events to help the young and the old in our local communities and to those in need. Corporate Social Responsibility is paramount to Navillus and Donal. After the 2010 earthquake in Haiti, Hurricane Sandy in New York, and Hurricane Irma in Florida, Navillus was first to jump in with emergency restoration, moving everything forward at its own cost. This is who Donal is.
In addition to being dedicated to Navillus and giving back to his community, Donal is a family man and is incredibly proud of all six of his children. If you know Donal, you are likely to know at least one of his children – and you will remember them. The O’Sullivan family is one who cares deeply about those around them and who are not afraid to share their outlook and personality with the world at large.
Donal is inspiring both inside and outside of the office. In looking at the NYC construction industry, Navillus is the story of a man who removed any ostentation from the picture and built a company that thrives because of its hard-earned reputation and compassionate leadership.
