More About Sarah

Hi, I’m Sarah, a psychodynamic, relational, and sex therapist in New York City. I work with adults and young adults navigating challenges related to sex and intimacy, relationships, trauma, anxiety, life transitions, and identity. Together, we’ll build a space that feels safe and attuned to your unique needs so you can move toward healing and meaningful change. 

Specialties & Who I Work With 

I specialize in supporting people who are: 

  • Navigating intimacy and relationship challenges 
  • Coping with infidelity or rebuilding trust in relationships 
  • Women struggling with anxiety, shame, or body image concerns 
  • Moving through identity shifts, transitions, or early adulthood 
  • Looking to reconnect with yourself and relationships in meaningful ways 

Sex, Intimacy, & Relationships 

Many of my clients come to therapy feeling disconnected from their bodies or uncertain about how to move forward after difficult sexual experiences. I support women healing from sexual trauma, those navigating shame around intimacy, and individuals seeking to rebuild trust after infidelity. In our work, I create a safe environment to process & work through trauma, shame, and reconnect with sexuality and relationships in a way that feels safe and empowering. 

Emerging Adulthood & Identity 

I work with college students and recent graduates facing the complexities of early adulthood. This life stage can bring unique challenges related to identity, independence, career uncertainty, and shifting relationships. I help young adults manage anxiety, self doubt, and new responsibilities as we build self trust and navigate the uncertainty of early adulthood. 

Body Image & Self-Esteem 

I work with women navigating body shame, social influence, and the pressure to be “perfect.” Together, we explore these patterns and social pressures as we build a more compassionate relationship with your body and self. 

Therapy Approach

My approach is relational and grounded in the belief that healing happens through connection. I integrate psychodynamic therapy with mindfulness in order to meet you where you are while exploring the patterns that shape your life and relationships. I value body positivity, sex positivity, and anti oppressive practice. 

Together, we’ll explore not just what you’re experiencing, but also how it shows up in your body and relationships. Therapy with me is collaborative and flexible; I show up as a real person, sometimes challenging and often with humor. Our work will blend insight with action, supporting meaningful change beyond the session. 

Background & Training
