    A love of architecture and nature brought Keith to his current field.  Keith graduated from the University of Massachusetts with a B.S. in Landscape Architecture in 1998 and went on to complete his MBA at Farleigh Dickenson University. His passion for design has driven him to create award winning and unique environments that cultivate a great respect for the natural world as well as human emotion. Years of experience creating, constructing and managing projects allow for a practical and intuitive knowledge of garden design which takes into account beliefs in conservatism and sustainability.
