Author Archives: Marvin W. Acklin, Ph.D.

My name is Marvin Acklin. I am a board-certified clinical and forensic psychologist practicing in Honolulu. I am very interested in psychology interfacing with the legal system. As I am a forensic generalist, I am involved daily in a wide range of cases. These include criminal (insanity and fitness to stand trial) and civil law (personal injury), child custody, personnel selection/fitness for duty, legal capacity assessments, and forensic risk assessment. We do violence risk assessments for the courts and private attorneys. I am a trained child forensic interviewer in cases of suspected child sexual abuse. I have diverse interests in medicine, law, history, theology, and clinical, assessment, social, and forensic psychology.
