About Us

A legacy of craftsmanship

Gentile & Co. is a full-service landscape architecture, planning, and environmental consulting firm in Jupiter, Florida, chartered in 1988.

Decades of local expertise, a passion for enduring places

For more than three decades, Gentile & Co. has improved the quality of life across South Florida by balancing and enhancing resources for our clients' success while respecting the community, the environment, and our shared future. We work effectively with both the public and private sectors, primarily across South and Central Florida, with projects reaching Georgia, Mississippi, North Carolina, Costa Rica, and the Bahamas and Caribbean.

Our team includes licensed Landscape Architects, an ISA-certified arborist, and professional planners recognized by the American Institute of Certified Planners (AICP), alongside LEED Accredited Professionals and a talented group of graphic designers — staffed to carry projects from concept through construction observation in-house. Most have practiced with the firm for a decade or more.
 

With this sustainable design process, we have delivered numerous LEED-certified projects — among them the Max Planck Florida Research Institute, Harbor Branch Research Institute at FAU, the Quantum Foundation Headquarters, Turtle River Montessori School, and the Ballpark of the Palm Beaches. We are also proud to be the planners who secured the first approval of a wind farm in Florida.
