My Approach
My goal is to help young people build resilience, improve their quality of life, heal, and achieve their goals through evidence-based therapies and a collaborative working relationship. I view my role as a guide — someone who can help you navigate challenging emotions, situations, and physical symptoms, so you can build your most meaningful and fulfilling life. I firmly believe that young people deserve comprehensive care from clinicians who understand the intersection of complex physical health and emotional well-being.
I utilize evidence-based interventions to support youth in therapy. These interventions have been scientifically evaluated and shown to help children and adolescents move toward their goals — whether that means managing anxiety, improving mood, or enhancing academic performance. Therapy is tailored to each individual, and progress is monitored through questionnaires and data to ensure that every young person is moving toward their outlined goals.
My approach draws on a range of evidence-based interventions, including cognitive-behavioral therapy (CBT), trauma-focused cognitive-behavioral therapy (TF-CBT), motivational interviewing (MI), acceptance and commitment therapy (ACT), elements of dialectical behavior therapy (DBT), exposure therapy, mindfulness-based interventions, and behavioral interventions.
