  • International projects: Bali, Indonesia, England, Italy, the Americas, China, and Caribbean

Background Overview:
George is credited with so many wonderful projects over his career—too many to list, as it all began in 1979. Initially, George worked with John Watson Landscape Illumination and established an office in Palm Beach, FL and Nassau, Bahamas. In 1982, he left this organization and established Caribbean Lighting Design and ultimately returned to the Palm Beach area. He performed his services throughout the world for elite clients and commercial projects for over 40 years.

Not only is George a lighting designer, but he is a photographer, pilot, and real estate agent. This brings an added level of insight and experience to our ELLI team. One of the aspects that most attracted ELLI to George was his means to address the challenges of landscape lighting design. George believes that lighting design doesn’t have to be done only one way—there are many ways in which to achieve positive results. He wishes to teach others so that they may find the confidence and ability to have their own style.

George is an innovator, too, as he learned many techniques during his early years with John Watson, Artistic Lighting, and William Wertz, as well as several architects, Burle Marx, John Randal McDonald, Carson Wright, Peter Marino and others. He worked with Peter Jackson of Wendel Lighting to develop new product designs. Because of this, George developed his own style of concealing light sources and selectively pruning trees to allow the internal illumination of these forms. He has been recognized for his glare-free designs and treating these environments as a ‘whole’—concepts specifically aligned with the ELLI approach.
