A Century of Building Trust. That is Hennessy Construction Services Corp. through and through.
A history, rich in tradition, began in 1920 when AEneas P. Hennessy, a young Irish immigrant, moved his family to St. Petersburg and founded A.P. Hennessy Construction. The company’s first major project, St. Mary’s Church (for the Catholic Diocese), continues to serve the St. Petersburg community today.
Ken Hall purchased the company from the Hennessy family in 1983, and in 1986 changed its name to Hennessy Construction Services Corp. Bronson Alexander was hired in 1988 and purchased the company in 1999. Mark Stalker joined the firm in 2009 and was promoted to President in 2015; he became Owner in 2017.
Under Mark’s leadership the company continues to thrive, establishing itself as one of the Tampa Bay area’s premier, quality-oriented contractors. Hennessy is a stable, close-knit group, with many working for the company for more than ten years. With a focus on customer service and satisfaction, Hennessy has completed more than $500 million in construction projects since 2014, much of it with repeat clients. Some of the more notable projects include St. Anthony’s Hospital, Jim & Heather Gills YMCA, St. Petersburg Catholic High School, Don Cesar Beach Resort, Mahaffey Theater, the Sundial, and the Museum of Fine Arts.
Our people are the reason for Hennessy’s continued success and steady growth. It is this combination of experienced professionals and powerful resources which enable Hennessy to provide clients with controls assuring the completion of projects on time and within budget.
