Nancy R. Williger, PhD

Nancy Williger, MSW, PhD, has almost forty years of experience working with individuals, couples, and families who are facing the struggles and changes that life brings. She is trained as a psychologist, a social worker, and a family therapist and is uniquely able to bring together individual, family, and societal dynamics to help people understand and develop solutions to their problems. She is specifically trained in approaches to conflict resolution and family mediation, which enables her to help couples stay together. If the decision to separate has been made, then she is also able to help the couple learn how to do this in a way that minimizes conflict and helps protect the children involved.

She states, “I am always honored that people are willing to share their most difficult moments with me and I am always learning from them, even after all these years.”
