Biography

Born in Walnut Creek, California, Dianne K. Conway grew up in Mt. Kisco, New York and completed high school in Bellevue, Washington. She then went on to receive a B.A. in Near Eastern Languages and Civilization at the University of Washington, an M.A. in Arab Studies from Georgetown University, and a J.D. at the University of Virginia School of Law. In between, she also worked in Washington, D.C. and lived in Syria and Israel before landing in Tacoma and joining GTH, where she seems to have finally settled down.

Dianne’s practice areas include environmental law, real estate litigation, natural resources law, and land use. Her commitment to these issues also extends to her life outside work. She has co-authored articles about environmental issues and litigation, and she served as a member and officer of the Board of Trustees of the AgForestry Education Foundation from 2007 to 2012. Dianne also served on the Point Defiance Zoo Society’s Board of Directors for 11 years, including as President, and was chair of the 2013 Zoobilee. Currently, she serves as President of the fabulous Symphony Tacoma.

Dianne lives with two lively and intelligent border collies, and she sometimes considers acquiring a small herd of sheep – or fulltime Frisbee thrower – to keep them occupied while she’s working. Dianne’s other interests include travel both near and far, exploring the outdoors, and enjoying great food and wine with friends.
