Scholarly Lectures and Writings:

  • Determining where a child will attend school for separated or divorced parents can be overwhelming. When parents share joint legal custody, they are required to make educational decisions together as co-parents. However, as family law professionals, we often see parties engage in high conflict, unilateral decision-making, and ulterior motives when it comes to deciding school choice related issues for their minor children. Rather than staying child-centered in these decisions, parents are often focused much more on their own needs in the process.  How then should we as family law professionals better approach school choice related issues? This article, co-authored with Amanda Crain and Katie Lammers of Heimerl & Lammers LLC, discusses the faults in the current approach to school choice, how this impacts children, and considers when and how school choice should be addressed when parents cannot or will not agree., Co-Author, School Choice: A Focus on the Child as a Learner, 2017
