Justin F. Hummer, M.A.

I strive to create a supportive and culturally-sensitive environment for individuals from all backgrounds to openly discuss whatever aspects of their identity are most salient to them, whether in clinical work, the classroom, or through the scientific work of Psychology.

Curriculum Vitae

The Jesuit concept of Cura Personalis is concerned with the care of the whole person and is at the center of my experience in Jesuit education and my own teaching philosophy. In many ways my own journey as a recipient of the teaching-scholar model is representative of how I plan to engage students and be concerned with their development of their whole persons. As a student of LMU’s Psychology Department, I was inspired by my professors’ passion for Psychology. They made Psychology come alive and always focused on the bigger picture and application of the concepts to real world settings. I was amazed by their willingness to challenge me and others on a personal level to be the Magis, ‘the more.’ I have learned as much from my experiences in the Jesuit educational landscape about how to be a more genuine person and member of society, as I have learned about how to be an effective scholar.

Testimonials

[Justin] made himself easily accessible and approachable. I was not afraid to ask questions because he would answer thoroughly and respectfully, no matter how obvious the answer should have been. He made sure to not just spoon feed us the answers, but actually help us understand the purpose behind certain steps in our labs.
— Student
[Justin is] smart, helpful, respectful, easy to talk to. Approachable.
— Student
He was so enthusiastic about the material that I felt we lost a bit of actual time to work on our assignments because he was so good at discussing the subject matter with us.
— Student
[He is] AMAZING. Always willing to help. Has so much patience. Walks you through it step by step and makes the information bearable. He really cares and teaches you well
— Student
I worked daily with Justin for over 6 years as his teacher, research mentor, boss, and colleague and I have witnessed his continued growth and development as a practitioner of clinical science since he entered graduate school. ... Justin is
an excellent scholar/researcher in his own right with his own voice—one that has been heard in the design of his own projects, first author publications, and the setting up of panels and delivering papers at APA and the Research Society on Alcoholism. ... He already is a significant and recognizable figure in the world of adolescent/college student/emerging adult addiction research and intervention, and I am convinced that he will have a substantial impact on the field throughout his career.
— Joseph W. LaBrie, Ph.D., Professor of Psychology
