Cliff Deetjen

Cliff graduated with a B.A. from Hobart College and received his Masters of Architecture degree from the University of Maryland. He and his wife, Kim, also in the interior design profession, lived in Boston where he worked with the large architectural firm Shepley Bulfinch. Enjoying the urban lifestyle, but a desire to move to "greener pastures", they chose the beautiful Champlain Valley to raise a family in 1998. With two older sons now and always a family dog underfoot, Cliff loves living in close to Burlington and enjoying all that the city has to offer. When not working around the house or involved in the gardens, Cliff can be found traveling and exploring architecture in other regions, or knee-deep in a river, and always with a fly rod in his hand.

Cliff's passion and interest in design stems from the huge appreciation of how the details come together in the field. He loves exploring with the Peregrine Team of craftsmen, how traditional methods and materials can be heightened to new levels, in a contemporary setting. Cliff has been with Peregrine since 2008 and looks forward to every project with enthusiasm and creating long lasting relationships with our clients.
