About Me

I am a New York State licensed creative arts therapist and Somatic Experiencing Practitioner working with adults, families, and children who are seeking to overcome their personal barriers using a collaborative approach that incorporates creative expression. My focus is on helping you explore your own capacity for healing within the framework of a safe and trusting therapeutic environment.  I use the artistic process, mindfulness-based interventions, and principles from Somatic Experiencing to help you increase your awareness and be able to meet life’s challenges with equanimity and authenticity.  I believe in the capacity of each individual to draw on existing strengths to remove present-day obstacles, as well as to delve into longer-seated issues that might keep you from reaching your full potential. As a native Spanish-speaker with multicultural roots, I also bring a unique and compassionate perspective to my work with individuals who are culturally diverse.

In addition to working with life stressors such as career dissatisfaction, relational conflicts, and parenting difficulties, my main areas of focus are:

  • Anxiety and Mood Disorders
  • PTSD and Trauma
  • Family and Parent/Child Relationships
  • Acculturation and Immigration Issues
