Getting to know Dr. John Koh

Dr. John Koh is a licensed clinical psychologist with over a decade of experience helping clients build resilience, deepen self-awareness, and navigate life’s challenges with confidence. Since 2011, he has provided personalized, evidence-based psychological care to adolescents, college and graduate students, young adults, and professionals in the greater Chicagoland area. Dr. Koh specializes in working with high-achieving individuals who are striving to balance ambition with personal fulfillment. He understands the unique pressures faced by students, professionals, and those in transition, and offers a compassionate, non-judgmental space to explore challenges, develop practical coping strategies, and foster meaningful, lasting change.

What should a new client know about working with you?

Dr. Koh is a licensed clinical psychologist who integrates Cognitive-Behavioral Therapy (CBT), mindfulness techniques, and goal-oriented strategies to tailor treatment to each client’s unique needs. He has extensive clinical experience treating ADHD, anxiety disorders, depression, and bipolar disorder, and is particularly skilled at helping clients untangle overlapping symptoms to get to the root of their struggles. In addition to therapy, Dr. Koh provides comprehensive psychological and neuropsychological assessments. These evaluations offer deep insights into cognitive abilities and assist with diagnostic clarification—whether for academic accommodations, medical treatment planning, or professional settings. He has performed evaluations for high schools, universities, medical practices, and forensic contexts. New clients often appreciate his calm, collaborative style and his ability to blend clinical expertise with genuine warmth, making even difficult conversations feel manageable and productive.

What is your typical process for working with clients?

Dr. Koh’s process begins with an in-depth initial consultation (typically 1–2 sessions) to conduct a thorough clinical interview. During this time, he takes a detailed history, explores your current concerns, and works with you to clarify your personal goals for treatment. From there, he develops a tailored plan that may include weekly or biweekly therapy sessions using CBT, mindfulness, and solution-focused techniques to address immediate symptoms and build long-term resilience. For clients with complex or unclear presentations—such as distinguishing between ADHD, mood disorders, or learning challenges—he may integrate neuropsychological testing to obtain objective data on cognitive functioning, which can refine the diagnosis and guide more targeted interventions. Throughout the entire process, Dr. Koh regularly checks in on your progress, adjusts strategies as your needs evolve, and ensures that treatment remains practical, collaborative, and focused on helping you achieve a healthier, more balanced life.
