Hello, we are MCDUFFTOURS LLC and we organize and lead tours to visit great gardens around the world.

We are retired professors from Virginia Tech in Blacksburg, Virginia. Robert is a Landscape Architect and was a professor of horticulture and director of the Hahn Horticulture Garden. Nancy is a soprano and former head of vocal studies in the Department of Music.

Over the past 20 years, we have taken over 1000 people to visit gardens here in the U.S. and abroad. These travels have taken us to England, Wales, Scotland, Ireland, Northern Ireland, Italy, Spain, Portugal, Monaco, Belgium, Germany, Austria, Switzerland, France, Canada, Japan, New Zealand, Australia, and the Netherlands.

It is our pleasure to share great gardens with people who love them.
