Lisa Marquis

Practice Description

Lisa Marquis believes in settling family cases collaboratively whenever possible. Her clients view the collaborative process as a way to better control the outcome of their case and reduce stress and trauma to their family. Divorce is certainly an ending, but Lisa also sees it as the beginning of a new family unit. She believes that the collaborative process can smooth the transition for you and your children. Lisa also understands that some cases cannot be handled collaboratively and also effectively represents clients in contested matters that are presented to the court for determination. However, even in those contested cases, Lisa uses her training as a collaborative attorney to minimize the level of conflict between the parties, and endeavors to always put the best interest of the children first.  Even in cases that need to be handled through the more traditional litigation process, Lisa strives to be part of the solution and not part of the problem.
