About me

I represent individuals in all matters affecting the family including divorce, complex financial matters, child custody and placement matters, as well as paternity, adoption, guardianship and estate planning.

I am trained and have extensive experience representing individuals in the collaborative divorce process and am an active member of the Collaborative Family Law Council of Wisconsin (CFLCW).  Specifically, I am the 2011 Chair of the CFLCW Board of Directors and served as CFLCW's Training Chair from 2007 to 2010. 

I am also a trained and experienced mediator assisting parents and couples in resolving child-related and financial issues privately and without court involvement.

I hold a Masters in Social Work and prior to practicing law was extensively involved in the advocacy and protection of abused and neglected children in Milwaukee. I continue my advocacy for children by serving as a Guardian ad Litem in family court matters.
