Cortex Development Group LLC (CDG), the development arm of Cortex Companies, was established in 2001 with the core focus of developing complex residential and commercial real estate projects in the Florida Keys, the South Florida coast and the Caribbean. The company is headed by two principals: Derek Parker & Everett Atwell, both native to Key West, who have pooled their professional talent and assets toward the goal of developing only top quality vacation, residential and marina products. Blending quality, environmentally-sound   development with the fragile infrastructure and environment of the Florida Keys is a key aspect of Cortex Companies projects. CDG manages and operates all of its projects in house. Each project is handled from inception to sale entirely by its own team. CDG maintains its corporate offices in the Tampa, Florida area and a local operations office in Key West, Florida. CDG is the premier developer of luxury lifestyle communities in the Florida Keys, with over $600 million in various stages of development.
