My goal is to transform the way we provide treatment for children and adolescents in crisis and enable care that nurtures and aids in their recovery.



As a clinical child psychologist, I specialize in working with children and adolescents who are having significant behavioral and mood-related difficulties. I have a strong background in behavioral and cognitive-behavioral therapy, as well as in a trauma-informed approach to care. I also have expertise in assessing and treating children and adolescents with neurodevelopmental disorders, such as ADHD and related difficulties.

As senior director of Behavioral Health Programming, I work with interdisciplinary teams to develop, implement, and evaluate interventions and programs of care in an acute-psychiatry inpatient setting.

In addition to helping patients, I conduct research. I have two primary areas of interest in my research. One is to understand, develop, and implement interventions to improve the lives of children and adolescents with behavioral and learning difficulties. The other is to understand and implement interventions for children and adolescents in acute-care settings that promote stabilization and recovery.

I approach care from an evidence-based perspective that is committed to the enhancement of health and well-being. I accomplished this by:

  • Using the best available clinical scientific evidence
  • Understanding and incorporating the values and preferences of each patient
  • Having strong clinical experience and training to inform how best to help each patient and their family

I was drawn to my career by my desire to empower children and their families to achieve their fullest potential. My goal is to transform the way we provide treatment for children and adolescents in crisis and enable care that nurtures and aids in their recovery.

For my own care, I am rejuvenated by being in the outdoors and backpacking with my family.
