Dennis became enamored with wildlife as a youngster in his native Costa Rica. Living in Central America, it is not difficult to see how biology could become the favorite science for any nature enthusiast, as there are several thousand species in the region. He has a passion for bird sounds and has a collection of them — recently he worked on the creation of a DVD that mixes the piano with the sounds of the birds.

His experience and knowledge has taken him to lead groups in other countries in Central America, South America, Africa, New Zealand, South East Asia, Australia, Russia, Alaska, the Arctic, the Antarctic, and the Caribbean. When he is not lecturing, Dennis travels to remote areas in Central America explaining to young students how fragile the ecosystems are where they live. He also works on several projects to monitor endangered species in order to improve conservation efforts.
