Constance Van Kley

Litigation Director

Constance Van Kley grew up on the Iron Range of Michigan’s Upper Peninsula, where she watched mining corporations create and then withdraw from small towns throughout the region, destroying livelihoods and landscapes.  She graduated from high school in Custer, South Dakota, a small town with a tourist economy in the Black Hills, and attended college in Minnesota.  Constance married a wildland firefighter, whose job as a smokejumper brought her to Montana.  When their first child was born prematurely, she and her husband were uninsured.  As a result of that experience, Constance and a group of hotshot firefighters organized a successful citizens’ movement, pushing the Obama administration to extend federal healthcare benefits to seasonal wildland firefighters and their families.

A nontraditional student with two children at home, Constance graduated first in her class from the University of Montana School of Law.  During her time in law school, she was elected Co-Editor-in-Chief of the Montana Law Review, participated in the Mediation and National Moot Court competition teams, and served as a teaching and research assistant.  After law school, she clerked for Chief Judge Sidney R. Thomas of the Ninth Circuit Court of Appeals and then-Chief Judge Dana L. Christensen of the District of Montana.  Constance worked in private practice before joining Upper Seven Law in July 2021.
