Our Philosophy
DSE is committed to providing the best service
possible, by listening to the client, and meeting their
needs.  DSE's goals are based upon delivering high
quality services designed to exceed client expectations
through commitment, accountability, and integrity.
Ecological Restoration
When DSE began in 1997, the original slogan was
"ecological restoration, from river, to tree, to sea", as
a representation of the biocycles of the natural
environment (freshwater, terrestrial, and salt water).  
"River" represents the freshwater biocycle.  "Tree"
represents the terrestrial biocycle.  "Sea" represents the
marine biocycle.  DSE's qualifications for restoring and
protecting the environment include all three biocycles.
