Mary York’s practice focuses on condemnation cases and real estate litigation. She helps her clients assess legal issues, evaluate resolution options, and achieve favorable outcomes.

As a former Deputy Attorney General for the Idaho Transportation Department, Mary gained broad experience in eminent domain cases and transportation- and construction-related matters. She now applies that experience to representing her clients, which include both governmental agencies and landowners alike, in condemnation disputes and other litigation matters. 

Mary is an experienced trial lawyer who understands the range of factors that contribute to litigation and settlement proceedings in these matters. She applies this knowledge to anticipate opposing counsel’s strategies and identify stronger positions for her clients on a case-by-case basis.
