Curriculum Vitae


To Contact:

Dr. Karen Jeanne Hummel (known to her students as “KJ”) has been teaching at Vanguard University since 2000, briefly as an adjunct instructor and soon thereafter as a resident faculty member. KJ teaches in the traditional undergraduate and the SPS adult learner programs, and she is especially interested in the formation of identity, according to God’s calling.

KJ takes great joy in being part of the Vanguard community, and she revels in getting to know the people who are her students. She delights in watching her students progress in self discovery and understanding so that they may relate to the world around them more positively and effectively as they grow and develop into the people that God has designed them to be. She is particularly interested in family and group dynamics, as well as personality, social, and abnormal psychology.

KJ grew up in Costa Mesa, California, and graduated as a psychology major with a bachelor’s degree from the University of California, Irvine before earning her masters and doctorate degrees in clinical psychology from the California School of Professional Psychology, San Diego in 1992. Before becoming a college professor, she worked as a psychological assistant in private practice and experienced human development through the process of parenting two sons and a daughter.

KJ and her husband, Jeff Scattareggia, are passionately involved in Stepfamily Ministry and are mentors in the Stepfamily Ministry group at Mariner’s Church in Irvine, California. KJ lives in Aliso Viejo, California with her husband and three children, AJ, Joshua, and Alexandra, and she and her family attend Calvary Chapel Pacific Hills.
