A history rich in tradition began in 1920 when Aeneas P. Hennessy founded A. P. Hennessy Construction in St. Petersburg, Florida.  Emigrating from Ireland at age 19, Aeneas went to Chicago first, but in 1917 he moved his familyto Florida. St. Mary's Church under constructionHis first project as A. P. Hennessy Construction was a project for the Catholic Diocese for a new cathedral. Today, St. Mary's Church still serves the community in downtown St. Petersburg.

Then, in 1975, due to union and open shop labor competition, it became necessary to establish a new company for open shop labor contracts, and so a sister company was born called Dara-Hennessy Construction Company. The Hennessy family retained control of the company until 1982, when both companies merged into Hennessy Construction Services with Ken Hall as the new owner.

 

Today,  Hennessy Construction Services is led by Bronson Alexander, President and CEO. Bronson started working at Hennessy in 1988 as a project manager. Working his way through the ranks, he became president in 1998 and purchased the company from Ken Hall in 1999.

Hennessy Construction Services is a close-knit group, with many employees who have worked for the company for more than ten years.  During almost 90 years in business, Hennessy has only had three owners - A. P. Hennessy, Ken Hall, and now Bronson Alexander.

Under Bronson’s leadership the company has continued to thrive and grow, establishing itself as one of the Tampa Bay area’s premier, quality-oriented contractors. With a focus on customer service and satisfaction, Hennessy has completed more than $300 million in construction projects since 1998, much of it with repeat clients. Some of the more notable projects include renovations to area landmarks such as St. Anthony’s Hospital, St. Petersburg High School, Don CeSar Beach Resort, Mahaffey Theater, and the Museum of Fine Arts, to name a few.


Hennessy Construction Services also gives back to the community by providing generous support for many local organizations and programs such as the Mayor’s Mentors & More, Doorways Scholarship Program, St. Petersburg Free Clinic, Pinellas Hope, YMCA of the Suncoast, YMCA of Greater St. Petersburg, The Salvation Army, St. Anthony's Hospital, Resurrection House, and Southeastern University
