Rahan Ali, Ph.D.


Philosophy of Care

Dr. Ali honed his engaging style of therapy through 20 years of experience. Patients benefit from his dynamic teaching skills as he guides them through treatment. His approach is active and results-oriented: collaborating with patients to target symptoms, identify areas of difficulty, and develop specific goals. He customizes a treatment plan utilizing cognitive behavioral therapy and other research-proven best practices for treating anxiety and related disorders.  His style blends warmth, encouragement, and a sense of humor, coaching patients to address problems wherever they occur. Patients learn to face uncomfortable situations and develop the self-confidence to manage their symptoms and live successfully even when symptoms appear.

Special Interests:

Dr. Ali is most interested in anxiety disorders, including social anxiety, phobias, obsessive-compulsive disorder, and panic. He is a passionate teacher, both in one-on-one therapeutic situations and in the community.

In his spare time he likes to read, listen to music and spend time with family. As a native Chicagoan, Dr. Ali loves the lake, Bulls basketball, and construction traffic (one of those isn’t true!). He also likes to play piano, especially when no one is listening!

Experience and Training:

Dr. Ali earned his Ph.D. in Clinical Psychology from Bowling Green State University and completed his internship at University of Cincinnati, where he specialized in treating anxiety, depression, and trauma. He completed a clinical fellowship at Northeastern Illinois University and a teaching fellowship at Penn State University. He has worked in numerous settings with a variety of clinical populations, and has extensive training in cognitive-behavioral and exposure-based treatments. In addition to his clinical experience, Dr. Ali also taught for several years in the psychology departments at University of Pennsylvania and Penn State University, where he was an award-winning instructor. He regularly offers presentations on anxiety and other mental health topics, and he enjoys educating the public as well as training other therapists. His professional affiliations include the Anxiety and Depression Association of America (ADAA), American Psychological Association (APA), International OCD Foundation (IOCDF), and the Association for Behavioral and Cognitive Therapies (ABCT).
