People are the reason for Hennessy's continued success and steady growth. It is the combination of experienced professionals and powerful resources that enables Hennessy to provide clients with controls that assure completion of projects on time and within budget requirements. By combining old-fashioned bricks-and-mortar hard work with high-tech computerized management, budgeting, and scheduling systems Hennessy has continued its tradition of excellence. Many of our employees have been with Hennessy for more than ten years and several for more than thirty!

For more than eight decades throughout Florida, Hennessy has completed many complicated and unique projects. It has always been the risky and challenging projects that have been the most satisfying and rewarding projects for the employees. Whether the project requires specialized laboratories and surgical suites or large amounts of uniform concrete, Hennessy has the experience to complete the work successfully. Consistency and attention to detail have enabled Hennessy to establish a large client base of repeat business.

     • Provide innovative construction solutions in an ethical and unified approach;
     • Provide the highest levels of quality, safety, and customer service;
     • Provide a fun, energetic work environment; and
     • Achieve a reasonable profit.
Community
As a corporate citizen, Hennessy has a responsibility to the community. Hennessy's annual objective is to help our community continue to grow and prosper. Through volunteerism, in-kind gifts, and community service we provide active support for many local charitable organizations and their causes. As an industry leader we also work for the betterment of the local construction market. Our strong relationship with industry organizations such as Associated Builders & Contractors helps us achieve our goal.
