The classical Family Constellation is done as a group process. If you want to get deeper in the method you can find more about it in the menu “Background Information / About Family Constellations”.
Since a Family Constellation is always the beginning of a process, a short follow-up session is included in the constellation fees. So you can be sure that you are not “left” alone with your feelings and thoughts. Obviously you are free to decide to not make use of this follow-up session.
