The CDE Team

At your service


CDE’s team of engineers and marine scientists are uniquely qualified with advanced engineering degrees and specialty board certifications.  Our engineers are invited to speak internationally at professional conferences such as the International Conference on Sustainable Infrastructure, International Green Building Conference in Singapore, Coastal Structures Conference in Italy, the American Shore and Beach Preservation Association annual conferences and Green Highways conferences.  We combine expertise in engineering and management with personal service and a hands-on approach.  Since our founding in 2000, we have provided exceptional service to our clients throughout the Caribbean and the Americas.

Several of our Principal and Senior Engineers have been awarded the prestigious designation of Diplomate in Coastal Engineering (D.CE.) by the Academy of Coastal, Ocean, Port and Navigation Engineers (ACOPNE).  ACOPNE provides this designation to recognize individuals who have excelled in coastal engineering with verified experience and contributions to the industry.
