Practice Philosophy

Attorney Cartier dedicates her practice to family and elder law with a focus on mediation and collaborative divorce.  She believe that the best resolutions are ones where the parties chose the less adversarial route and engage fully in the process.  This process not only saves time and money, but is a healthier way for folks to resolve their differences. With Cindy’s extensive legal background over the last quarter of a century in many areas of the law, she has a unique ability to see the conflict from both sides of the situation helping clients to do the same.  She believes passionately in the process and it shows in how she cares about the parties both during and beyond the process.  She does not give up helping the parties resolve the issues and her dedication to this work leads to positive resolutions for years to come.
