All full-time members of the psychology faculty have earned doctorates and have different specialty areas within the field of psychology. Our students say that psychology professors care deeply about their students both in and out of the classroom; they are well trained in their field; and they are both challenging and interesting in the classroom.

Faculty research areas include studying Amish adolescents, adolescents’ understanding of God, children’s views of parents, issues in Christian higher education, research ethics, multicultural approaches to marriage, cognitive processes involved with distracting tasks, the psychological effects of technology, and the physiological responses to stress during learning. Our faculty members also see importance in cross-cultural experiences and the impact that traveling abroad can have on an individual. They strive to offer insight from their own cross-cultural experiences as well as opportunities for students to experience other cultures during their four years at Messiah.

Our psychology faculty are diverse in many areas, not only in their areas of interest or their professional background, but also in the ways they discovered their passion for the field. In addition to being published researchers/scholars, our faculty are seasoned professionals with firsthand experience in their areas of specialization. They aptly incorporate their own education with their clinical and field experience to provide students with invaluable learning opportunities in the classroom. Featuring age, ethnic, and gender diversity, our professors are also caring, committed Christians who want to see their students grow and mature academically, spiritually, and personally.

Our department is 7 full-time members strong. We are all located in Boyer Hall on the 3rd floor. Below you will find information about each member!
