Lisa is committed to helping to empower her clients by providing them with the information they need to make educated and informed decisions about the important legal issues affecting their lives. Her practice is focused on helping people resolve their real life conflicts and legal problems with grace and integrity. She assists and supports her clients in navigating the necessary court processes and provides the information they need to make the right decisions for themselves and their family. She follows a practice model that focuses on mediation, collaboration, alternative methods of resolving conflict and creative problem solving to find solutions to personal and family issues that avoid unnecessary adversarial positioning, costly court battles and the bitterness often associated with divorce and custody disputes. After over 30 years of a civil and family law litigation practice, Lisa no longer directly represents clients in contested court matters as her primary approach is helping clients resolve their legal issues without court intervention and as economically as possible.
