Kerrie Armstrong, Ph.D.


Philosophy of Care:

Thoughtful, dedicated, and focused, Dr. Kerrie Armstrong approaches clients with empathy, creativity, and a sense of humor. She works diligently to find the best path toward good health, adapting treatment methods based on each individual’s unique circumstances. She uses her vast training in anxiety disorders to diagnose and treat generalized anxiety, social anxiety, panic disorder and OCD. She utilizes cognitive behavior therapy, exposure therapy, and a variety of treatment methods proven effective in overcoming anxiety disorders. Working together with clients she normalizes the experiences of anxiety and helps clients to internalize more effective thought patterns and behaviors. Dr. Armstrong’s goal is to meet her patients where they are on their journey and build on their strengths using empirically supported treatments that suit them best. She believes in empowering people to become their own therapists by teaching skills they can use for a lifetime.

Special Interests:

Dr. Armstrong specializes in treatment for OCD and OCD spectrum disorders (BDD, trichotillomania and dermotillomania), in addition to generalized anxiety, social anxiety, and panic disorder. She applies cognitive behavior therapy and exposure therapy to effectively reduce symptoms and improve overall well-being.

A risk-taker herself, Kerrie exercises her adventurous spirit through skydiving, wall climbing, and ziplining, (but she doesn’t make her clients participate!). An outdoor enthusiast, she likes to run and hike, followed by relaxation with a good book or spending time with family.

Experience and Training:

Dr. Kerrie Armstrong earned her Ph.D. in Clinical Psychology from Rosalind Franklin University of Medicine and Science (formerly the Chicago Medical School). She has trained and conducted research with several leading experts in the anxiety field and has experience with cognitive-behavioral therapy and exposure therapy in the treatment of anxiety disorders, OCD, and OCD spectrum disorders. She completed her postdoctoral fellowship at Saint Louis Behavioral Medicine Institute where she specialized in the intensive treatment of severe anxiety disorders under the training of Dr. Alec Pollard. She gained additional specialized expertise at the OCD Residential program at Rogers Memorial Hospital in Oconomowoc, WI. She has presented at several conferences and is a member of the Anxiety and Depression Association of America (ADAA).
