Evidence-Based Therapies

Evidence-based therapies ensure each child receives care grounded in the most current research and proven clinical methods, supporting meaningful and lasting progress. CBT and ERP are both rigorously researched, gold-standard approaches backed by decades of clinical evidence and consistently shown to be highly effective for treating anxiety, OCD, and related concerns.

CBT Cognitive Behavioral Therapy Lexington, MA Dr. Kelly Ann Colby, Psy.D.

Cognitive Behavioral Therapy (CBT)

CBT is a structured approach that helps individuals identify and change unhelpful thoughts and behaviors. By learning practical coping strategies, clients can reduce anxiety, improve mood, and navigate challenges more effectively. CBT empowers clients with skills that work across settings to recognize patterns of thinking that fuel distress and replace them with healthier, more balanced ways of responding.

ERP Exposure Response Prevention Therapy Lexington, MA Dr. Kelly Ann Colby, Psy.D.

Exposure Response Prevention (ERP)

ERP is a specialized form of CBT and has been recognized as the gold standard of treatment for OCD. ERP is also highly effective for specific phobias, social anxiety disorders, and some forms of panic disorders. ERP helps individuals face feared situations in a safe, controlled way. By gradually reducing avoidance and compulsive behaviors, clients learn to manage anxiety and regain control of their lives.

Thriving academically starts with emotional support

Growing up today comes with big expectations — especially in high-achieving communities like ours. I help children and teens build resilience, confidence, and healthy coping skills so they can thrive both in and out of the classroom.
