About Me

I am a clinical psychologist with more than 10 years of experience working with patients living with chronic digestive illness. After training at the Center for Psychosocial Research in GI at Northwestern University, I started a private group practice in 2012 which has grown to meet the needs of patients living with IBS and other chronic conditions. My approach to treatment is to teach clients skills that will last a lifetime so they can better self-manage issues that come with having a chronic illness; as such, I find hypnotherapy to be an excellent tool to reduce IBS symptoms and improve quality of life.



I am a licensed clinical psychologist and director of adult behavioral medicine at Oak Park Behavioral Medicine LLC, an independent practice of clinicians specializing in the treatment of chronic digestive illness. I have specialty training in health psychology, cognitive-behavioral therapy, and medical hypnotherapy. In addition to my role at Oak Park Behavioral Medicine, I am a Research Assistant Professor at Northwestern University Feinberg School of Medicine. I have researched the psychosocial issues people living with chronic digestive conditions face since 2004, publishing several articles and three book chapters on the social and emotional aspects of these conditions.
