Mary Pfeiffer, Ph.D.
Director of Training

Licensed Clinical Psychologist since 1989

My current role at Adler University is primarily focused on the administration of an APA-accredited pre-doctoral internship program and overseeing externship training at partner sites with Adler Community Health Services (ACHS). I provide supervision and training to externs (in both assessment and therapy practica) and doctoral interns practicing clinical work in the community.

I have been a practicing clinical psychologist for 28 years, with strong interests in psychotherapy, assessment, and supervision/training. I maintain a small private practice and have held several positions at agencies and educational institutions. Most of my clinical experience has been treating and consulting marginalized populations experiencing severe mental illness, and as a program administrator, I have also been actively involved in the training of psychology graduate students.

Please email or call me at 312.662.4044 if you have questions or would like more information about me.
