School: Clinical Psychology
Dr. Carol Humphreys received her PhD in Philosophy (Clinical Psychology) from Miami University in Oxford, Ohio. Her dissertation focused on a single case study covering over 300 therapy sessions with a woman experiencing extreme internal multiplicity.
Carol began her college education as a single mother and received her AA from Cypress College in Cypress, California. She then transferred to California State University, Dominguez Hills (CSUDH) where she completed a dual major (BA) in English Lit and Psychology. Carol then received an MA in Clinical Psychology with an MFT option. It was there where she was first introduced to both psychotherapy research and, most importantly, Humanistic psychology. While at CSUDH, she focused on research with Art Bohart, PhD aimed at exploring the change process that occurs in therapy.
After graduation, Carol worked as a social worker in downtown Los Angeles. It wasn't long before she realized she missed academia, research and theory. Despite good intentions to keep up with the current psychotherapy research, she found it often did not resonate with or connect to her field work and practice. Learning more about how to link theory to actual practice became a bit of a mission for her.
Immediately after her children went off to college and adult life, she moved to Ohio to pursue her PhD. At Miami, she continued her interest in psychotherapy research. She was honored to work closely with Larry Leitner and Bill Stiles, both prolific writers and important mentors in her professional growth. Dr. Leitner's development of Experiential Personal Construct Psychology (EPCP) guided her growth as a clinician. Dr. Stiles' work with the Assimilation of Problematic Experiences Model (APES) allowed her to look at the process of change as it occurred within the therapeutic dyad. Miami's pluralistic theoretical model introduced her to a number of theories and theorists. It allowed her to explore Humanistic, psychodynamic, relational, existential and archetypal psychology.
Since receiving her PhD, she has taught both undergraduate and graduate courses in clinical psychology at Saybrook University, Miami University, Chapman University and Brandman University. She has taught psychopathology, abnormal psychology, cognitive psychology, humanistic interventions, psychotherapy, group therapy, marriage and family therapy, developmental psychology, assessment and treatment of substance abuse, counseling skills, social psychology, history and systems, practicum, colloquium, and research methods.
As a clinician, she has practiced humanistic and existential psychology within traditional (Community, hospital, and school) clinical settings. In addition to the psychotherapy, assessment and consultation she has provided at a number of community mental health centers, school sites and detention facilities, she has also provided therapy for adults, college students, adolescents, children, and parents. For four years, she has been a staff psychologist offering these same services to individuals committed to a forensic state hospital (Napa State Hospital) for individuals considered by the courts to be Not Guilty by Reason of Insanity (NGRI).
