Comments on Trainings and Talks


  • Dr. Langman’s presentations were well received and provided our community and school personnel with facts and suggestions related to school shootings and prevention that were timely and informative. Dr. Langman’s research related to Why Kids Kill left us with a knowledge base and understanding that will assist us as we work with our students in the future.
    — Dr. Jill Janes, Superintendent of Schools, Hannibal, Missouri
  • Dr. Peter Langman has studied and described the psychology of school shooters as deeply as anyone in our country … For any organization that wants its employees and community to more fully understand the psychological conditions of potential school shooters, Dr. Langman’s presentation and perspective will facilitate a more grounded and thorough understanding of this unfortunate phenomenon.
    ​— Dr. Joseph B. Moore, President, Lesley University
  • Dr. Langman’s information was clear and concise, shedding much needed light toward understanding the motivation of today’s youth who contemplate rampage school violence … Few who study school shootings have delved as deep as Langman into the often murky and troubled minds of these predators.
    — Samantha Dutill, Associate Executive Director, National Behavioral Intervention Team Association
  • Dr. Langman’s presentation was one of the best forums we’ve had in our many years of putting on these events. The presentation was so rich in substance and relevant to all five of our concentrations that students are still speaking about how wonderful it was and how we’d love to have him back. It was an amazing presentation.
    — Lisa Corbin-Kalinowski, Field Placement Coordinator, Holy Family University
  • The positive feedback from counselors in attendance for Dr. Langman’s workshop has been overwhelming.

Comments from Easton Area School District

  • “I found Dr. Langman's presentation on Preventing School Shootings to be both informative and thought provoking. Specifically, he dispelled a lot of myths about school shooters and provided a detailed look at the various psychological types based on actual events and journal entries. As a school counselor, I am involved in risk assessments from time-to-time and now have a greater awareness of the importance of creating a multidisciplinary team and steps to take in order to conduct an expanded investigation. I also believe I have a better understanding of what to look for and how to proceed in such cases.”
  • “Dr. Langman provided an excellent overview of psychology of the school shooter and the importance of establishing school communication/protocols/threat assessments as proactive approach to protecting a school community. The topic is extremely timely, as was his practical suggestions to managing such concerns. By using case studies to illustrate his points and by engaging the audience in active discussion, Dr. Langman kept his presentation relevant.”
  • “Listening to Dr. Langman's presentation was truly a privilege. Initially, I was overwhelmed with the idea of a four-hour training. Honestly, the time went quickly. Dr. Langman was very knowledgeable about the psychology of a school shooter and what can be done to prevent these tragic situations. This training was one of the best I have ever been to.”
