Attorney Profile

Most people agree: court is the least preferred place for divorce. Divorce is hard enough without a court battle, and the outcome can have a lasting effect on your finances, children, and relationships. Mark helps his clients reach agreements so they do not need to go to court.

Mark works as a divorce mediator and Certified Divorce Financial Analyst to help people work towards mutually satisfactory agreements. He also works as a Collaborative Lawyer in the Collaborative Divorce process. In either process, Mark focuses on helping you reach an agreement that fits your needs and is based on your priorities and goals, and your own choices. Not only are such agreements usually more satisfactory, but they tend to increase the ability to co-parent and to reduce future conflict.

Mediation and Collaborative Divorce are private and confidential. The resulting agreements normally address all issues in divorce, including property division, parenting plans (custody and visitation), spousal maintenance (alimony), and child support. The court's role is limited to signing off on your agreements.

Mark has practiced law since 1987 and is experienced in both family law and collaborative law. He was 2005 Attorney of the Year of the WSBA Family Law Section, and is a Fellow of the American Academy of Matrimonial Lawyers.
