About Us Jonathon Frantz discovered that the community of Post Falls did not have ample law resources and help for its community members. He realized that a law firm needed to be established in Post Falls. He also knew that to accomplish this goal he would need to team up with one of the best family law attorney’s in North Idaho, Jillian Roderick. Together, with their impressive skills and experience, they are anxious to provide the law services, counsel and help the beautiful city of Post Falls needs.
