Bill O’Donnell was a proud graduate of Villanova University where he earned his degree in Civil Engineering in 1965. After working for CertainTeed and Day & Zimmerman, he served for two years as an engineer in the U.S. Army in South Korea. In 1968, Bill joined the firm of Seymour W. Greenberg. Bill’s classmate at Villanova, Pete Naccarato joined the firm in 1974 and the firm was renamed Greenberg, O’Donnell & Naccarato. In 1981, the name changed to O’Donnell & Naccarato and the company as we know it today was founded in the historic Bourse Building in Philadelphia.
Over the past three decades, Bill spearheaded many notable projects in the Philadelphia region, including: Villanova’s West Campus expansion, a new science building, and expansion at Roman Catholic High School, the renovation of Saints Peter & Paul Cathedral, the King of Prussia Mall parking garages, and Harrah’s Chester Downs Harness Racetrack to name a few. In addition, Bill was heavily involved in the renovations of the historic Bourse Building where his company was founded as well as the renovations of the historic Lit Brothers Building where the company now resides.
Bill will forever be a part of the soul of O’Donnell & Naccarato, the company that bears his name. He was a dynamic leader, a stalwart supporter, a loyal friend, and an empowering mentor with a vibrant spirit and a calming presence. Bill’s “people first” approach is still evident within our company in both his unwavering support and friendships with our clients. His impact on the construction community of the Philadelphia area was widespread and will continue to contribute to our present and future successes for decades to come.
