What Carlton Research can speak to
Carlton Research can speak to pattern analysis (coercive control breadth, depth, escalation, entrapment, and more). Research is built to the evidentiary rules of the jurisdiction that will hear it. Carlton Research does not recommend parenting time or custody. Research establishes whether a pattern of coercive control is present. Inquire about specific testimony requests or speaking engagements.
