David Rigall is a registered landscape architect in the United States.  He has had his own design practice since 1988 and has had experience in many climate/plant zones.  His design firm, Rigall/Design, is active in the state of Florida, USA.

He has had an interest in history and in particular the history of gardens since attending the University of Michigan.  Several years ago he taught a course to architectural students at the University of South Florida, introducing them to the full breadth of the history of landscape architecture.  GreenHistory is the logical follow-on expression of this experience and my interest in sharing the intriguing view of gardens as seen through their history.

This website represents a combining of a design practice and the beginning of a garden tour venture.  Rigall/Design is mature and active and looking for new adventure, GreenHistory is new and finding ways of sharing the joy of being in a garden.
