ACT/CBS Background and Training: I earned my Bachelor of Science degree from Northwestern University and completed both my Master’s and Doctorate in Clinical Psychology at the Illinois School of Professional Psychology. As part of my doctoral training, I completed an intensive clinical internship and advanced therapy practicum at Gateway Foundation, where I provided individual and group psychotherapy in a residential substance use treatment program. I also developed specialized expertise in comprehensive psychological and diagnostic assessment through clinical roles in a psychiatric nursing facility and a college counseling center. In addition to my clinical work, I teach graduate students the principles and application of Acceptance and Commitment Therapy (ACT).
My diverse training has provided a strong foundation in evidence-based assessment and treatment across a broad range of emotional, behavioral, and life-transition concerns. For more than 15 years, I have maintained a private practice with a primary focus on ACT, helping clients build psychological flexibility, navigate distressing emotions, and create meaningful, values-driven change in their lives.
Throughout my career, I have had the privilege of working with adolescents and adults facing complex mental health challenges, including substance use disorders, depression, anxiety, bipolar disorder, eating disorders, post-traumatic stress, and co-occurring conditions. I also spent several years as part of a multidisciplinary medical practice, where I received advanced training in nutrition and neuroscience. This experience continues to inform my holistic and compassionate approach to psychological care.
Currently, I teach graduate-level psychology courses while providing psychotherapy to individuals across the United States through my private practice. My clinical specialties include addiction, anxiety, mood disorders, trauma-related conditions, chronic health conditions, and eating-related concerns. As a clinical psychologist, I take an integrative and collaborative approach to treatment, with particular expertise in Acceptance and Commitment Therapy. I am deeply committed to helping individuals strengthen resilience, enhance emotional well-being, and move toward a life guided by their personal values and sense of purpose.
