EMDR Therapy for Grief and Trauma

  • EMDR (Eye Movement Desensitization and Reprocessing) is an evidence-based therapy designed to help adults and children heal from trauma, loss, anxiety, and difficult life experiences. Through guided sessions, you’ll learn to process painful memories in a way that reduces distress and creates emotional balance, helping you regain control and move forward with resilience.

Resilience Training for Kids

  • We specialize in helping children under seven develop essential skills for navigating life’s challenges. Our approach includes teaching distress tolerance, impulse control, and emotional regulation, all while working closely with parents to reinforce these skills at home. Through playful and supportive techniques, kids gain confidence, build resilience, and learn to express their feelings in healthy ways.

Living room with a light blue sofa, a yellow armchair, a wooden coffee table, a side table with a lamp, and throw pillows and stuffed toys on the furniture. Large windows with white blinds are on two walls, and a patterned rug covers the floor.

Individual Therapy for Everyone

  • Our individual therapy sessions are tailored to meet each client’s unique needs. Whether you are dealing with grief, trauma, anxiety, stress, or body image concerns, we work collaboratively to identify your strengths, develop practical coping strategies, and guide you toward a more fulfilling life. Therapy is client-centered, strength-based, and focused on helping you thrive.
