In custody court litigation approximately 30% or more of these cases involve allegations of coercive controlling violence (CCV). Dr. Mann is an expert on Domestic Violence and has taught the required classes that are mandated that child custody evaluators take annually. Dr. Mann first became involved in domestic violence in 1981 when he worked at women shelters in Long Beach, CA with Charter Hospital and the Norwalk/Lakewood Sheriff’s department. Dr. Mann was appointed by a Family Court Judicial Officer to be a member of the Orange County Family Violence Council on which Dr. Mann served. Domestic violence is a pattern of behavior where one or both partners try to control or manipulate the other through fear and intimidation. This pattern can be of emotional abuse, physical gestures, financial control, verbal abuse or physical abuse. Most often there is a primary aggressor but on occasion it may be bi-directional. Dr. Mann has found the allegations of domestic violence are often used as a weapon to try to gain custody during custody litigation. Dr. Mann has also found that the use of threats and intimidations is often done covertly with threats of gestures and emotional abuse that are often missed in child custody evaluations by evaluators because they have not dug deep enough or failed to understand the real dynamics CCV. The studies are clear that children who witness domestic violence are negatively affected by this pattern of behavior which can lead to major psychological problems as children and as adults. Dr. Mann’s knowledge and experience in this area is extremely helpful to attorneys and clients when reviewing Custody Reports to insure these issues were properly evaluated and assessed.
