Psychotherapy ISTDP
Intensive Short-Term Dynamic Psychotherapy (ISTDP) is a evidence-based treatment approach that rapidly addresses anxiety, depression, and trauma. This method helps patients confront suppressed emotions through structured sessions that typically last 3-6 months. The treatment begins with a comprehensive 3-hour evaluation to identify core issues and develop targeted interventions.
Individual Consultation
Personalized mental health consultations help patients understand their specific challenges and treatment options. Initial telephone screenings determine therapy suitability, followed by customized treatment plans. Sessions occur weekly or biweekly in 60-90 minute increments, focusing on patient-specific goals and emotional growth.
Professional Supervision
Professional supervision services train mental health practitioners in ISTDP methodology. This includes case consultation, technique refinement, and treatment planning. Supervision combines academic instruction with practical application, preparing professionals to implement ISTDP effectively in their practice.
