Dr. Hartl (PSY20151) received her PhD in Clinical Psychology from the University of Connecticut in 2002. Prior to graduate training, she worked under the mentorship of Professor Randy Frost at Smith College to develop a model of compulsive hoarder behavior. During her graduate training, she completed a rotation at Dr. David Barlow’s Center for Anxiety and Related Disorders at Boston University and later received clinical training at the OCD Clinic at Mass General Hospital. Dr. Hartl completed her internship and fellowship training at the VA Palo Alto Health Care System (VAPAHCS). She served as a Clinical Instructor at Stanford University and as the Coordinator of the Anxiety Clinic at the VAPAHCS between 2005 and 2008, where she supervised practicum students, interns, and post-doctoral fellows in providing evidence-based care to individuals with anxiety disorders and sexual dysfunction. She has also served as a Co-Coordinator of the Sexual Dysfunctions Clinic at the VA. She currently teaches an Anxiety Disorders class at the PGSP-Stanford Psy.D. Consortium. In her clinical practice, Dr. Hartl specializes in evidence-based treatment (including exposure and response prevention) for adults with mood and anxiety disorders, stress, sexual dysfunction, and compulsive hoarding. She has conducted numerous workshops and has written scholarly articles on these topics.
