As the daughter of a Navy pilot, Tiffany moved frequently but always returned to her hometown of Bigfork, MT every summer since grade school. She practiced insurance defense litigation in Billings and Great Falls, and clerked for a federal magistrate before returning to the Flathead Valley where she opened the Lonnevik Law Firm on January 1, 2001. She is married with two sons and three step-daughters: one engineering student, one pre-med student, and three high schoolers. She enjoys riding her horse, traveling, and spending time at her lake cabin.
