About The Constellations Group
The Group's Mission
The four founding partners of The Systemic Constellations Group, LLC, came together in early 2005 to promote and facilitate systemic constellations for the understanding, healing and evolution of communities, families, and organizations.
They are among the leaders in introducing constellations in the United States and have facilitated many workshops in the Washington DC area. Attendees at their workshops have described their participation as astoundingly powerful.
The partners have had extensive training with world leaders in family and organization constellations in the United States, Germany, and the Netherlands. They are grounded in the Bert Hellinger approach to constellations and graduated from the Hellinger Institute USA year long program in 2002.
Their diversity of professional background and experience brings a rich variety to their perspective and facilitation of constellations.

Mary Rentschler
Mary Rentschler, M. Ed., combines twenty-five years of experience in learning and emotional problems with Educational Kinesiology and Family Constellations. Her clients identify key issues, come into balance with themselves and awaken hidden potential. She teaches and lectures on Educational Kinesiology nationally and deals with a wide range of 
learning, performance and emotional issues in her private practice with children and adults. She has also studied extensively with Dr. Svetlana Masgutova at the International Institute for Movement Development and Reflex Integration in Poland. Dr. Dietrich Klinghardt‘s five level model of health is a major influence in her practice. Since 2001 Mary has been involved with Family Constellations, which resonate deeply with her own philosophical and spiritual orientation to healing. As a member of the professional advisory board of Developmental Delay Resources, she is also active in bringing Family Constellations into the community of parents and professionals involved with autism spectrum disorders.
With children or adults for whom attending a workshop is not feasible, Mary offers individual Constellations using wooden figures as surrogate representatives. While neither as rich nor as precise as work with representatives in a workshop, the figures can provide an entry way into the "family field." For an individual constellation, the figures are arranged on a table or within a defined space in the room to represent family members or significant people in a particular system.
