aatc_doctorsFor over 20 years, The Anxiety Treatment Center of Greater Chicago (formerly the Anxiety & Agoraphobia Treatment Center, Ltd.) has been the source for the best anxiety care in Chicago and the North Shore. Led by the renowned Dr. Karen Cassiday, our team of clinical psychologists offers proactive solutions for your anxiety.

Our doctors all have PhDs or PsyDs and are specially trained to treat anxiety, phobias, OCD, panic attacks and other stress-related disorders. We utilize cutting-edge treatment techniques that actively involve each patient in the process of recovery.

We pride ourselves on offering the most advanced and compassionate treatment available. Our experts teach patients the skills they need to overcome their fears with sensitivity and a sense of humor, providing you with the tools you need to regain control of your life.

Our practice is recognized nationally for treating complex adult patients.  We are also particularly skilled at working with children, and provide parents with the resources and guidance they need to help their children succeed.

We can help you overcome the problems that fear has caused, and teach you to manage your fears, worries, and compulsions to live a life with confidence.

Results Oriented Treatment

Our treatment works by systematically exposing you to fearful situations. Our therapists teach you to modify thought patterns using cognitive behavioral therapy, exposure-based therapy, and mindfulness training, resulting in diminished symptoms within a short period of time.  This cost-effective approach empowers you to overcome your fears, restoring peace of mind.

Where you Need it Most

In addition to meeting you in our offices, our therapists can conduct sessions in your home or wherever you feel the most anxious. We have worked with patients in settings as varied as schools, offices, elevators, malls, and airplanes, enabling you to gain confidence in real-life situations.

Team Approach

For more complex patients, our team of specialists can mobilize quickly, providing customized, intensive treatment. Our unique, multi-modal approach works rapidly to restore good mental health, even helping to avoid hospitalization for the most severe cases.

  • Testimonials

    We were struggling for eight months with our son’s anxiety over sleeping. I reached out to the Anxiety Treatment Center and with our therapy sessions we worked out an expected timeline, plan and full support. Dr. Pojas educated me along the way so I understood the philosophy of the treatment. We were able to conquer my son’s nighttime anxiety. As parents we gained the necessary skills to help our son combat his anxiety and most importantly, so did he. We are all now partners in helping my son succeed in life. We are extremely grateful.
    A Grateful Mother
    Dr Zayed has been absolutely wonderful in helping our daughter (and me too!).  She did a phenomenal job relating to our daughter’s fears and concerns, meeting her where she was at, and pushing her just enough with positive encouragement to face her fears and overcome some very stubborn anxiety patterns that we couldn’t eliminate prior to coming to the center. She was patient, helpful and always put forth extra effort day or night to help our daughter achieve her goals in the most conducive way possible.  Her confidence grew and Dr. Zayed gave her great tools to use in the future. You are very lucky to have her as part of your practice and we are even luckier we found her!
    A Grateful Mother
    My daughter struggles with anxiety and trichotillomania. As her mother, I felt completely helpless and didn’t know where to turn. When my daughter started working with Dr. Schmaus, I quickly noticed a difference in her behavior and her overall anxiety. He helped her build coping strategies that she has been able to use to handle challenges in her everyday life. I am so grateful for the support we all have received at the Anxiety Treatment Center and specifically from Dr. Schmaus.
    Mother of an 8-year old girl
    I had encountered problems with anxiety and depression in the years since becoming a graduate student. My anxiety issues really put my education and career goals at risk and, indeed, threatened to end the pursuit of a career I love. With a lot of diligent work, and the advice and techniques provided by Dr. Schmaus, I am happy to say that I am in the last months of graduate school and am on track to graduate with very high marks from my teachers and instructors. I could not have done this alone and am very appreciative of Dr. Schmaus for all his efforts on my behalf.

    Working with Dr. Cassiday was a pleasure, she has a very calming and soothing demeanor.  She immediately ‘got’ my child and made him feel as though his feelings and needs were all that was important when actually she was really trying to change his behavior. She was also great with me as a parent, knowing I had my child’s best interest at heart, but showing me different ways to get the same results. I feel very fortunate to have Dr. Cassiday as part of our life!
    Grateful Parent
    Our son has gone from an anxious child who refused to go to school to a confident college sophomore who has the tools to manage his own anxiety.  The psychologists at ATC led us down this path with humor, sensitivity, and positive techniques, teaching us how to support our child and enabling our son to feel like he can confidently control his own symptoms.
    Parent of a College Student
    I had sought help for my phobias, anxiety and related problems for so long that when I started therapy with The Anxiety Treatment Center of Greater Chicago I knew right away that someone finally “got it”.  Their doctors have in-depth and up-to-date knowledge of anxiety, and they effectively applied their knowledge to help guide me from clarification of my problems to management and resolution.  I never left their office without a specific plan on how to move forward.
    Patient Who Had Previously Tried Many Different Therapists
    My children have been able to gain the necessary skills to manage their OCD at times of crisis because of the knowledge, caring, and expertise of Dr. Cassiday.  She was able to guide us through some very difficult times and help give our family the skills (using cognitive behavioral therapy and exposure and response prevention) so that our family could get back to normal. She was always there with us, and she still is.  She is so kind and so gifted in her field!
    Parent of 2 Children with Anxiety Disorders
    I really appreciate how The Anxiety Treatment Center of Greater Chicago has helped me to face my anxiety. When I started treatment, my anxiety was taking over, making simple tasks very difficult.  The doctor diagnosed my specific anxiety disorder and built an individualized plan to help treat it by using exposure therapy and other techniques.  Working with her has given me the confidence to face a situation head-on and overcome its challenges.
    Confident Female Patient
    Dr. Cassiday changed my life.  She took me on “field trips” to wherever was necessary to deal with my OCD triggers. She never hesitated to get down in the trenches with me and teach me new ways to respond. She was truly a partner in my healing.  We laughed a lot together, so what could have felt pretty miserable, actually was often quite fun. And after we extinguished the rituals, we worked on changing my thought patterns.  So now I am less anxious and more productive than ever before in my life, including before I developed OCD.  And the techniques I have learned help me in ALL aspects of my life, not just with the OCD.  I couldn’t be more grateful to her.
