Clinical Psychology

As a clinical psychologist, I specialize in helping children, teens, and young adults with cancer, along with their caregivers. I emphasize patient- and family-centered care. I work with patients and their families at all points on their cancer journey, including during treatment, throughout survivorship, and at the end of life.

I have expertise in easing anxiety and depression so my patients can deal with the challenges and changes that come along with a cancer diagnosis. I help them develop effective coping skills and improve their overall resilience and quality of life. I work closely with my patients’ care teams to provide the highest standard of care.

My research looks at developing screening processes to identify young patients and families who might benefit from social and emotional care. I am interested in understanding how teens and young adults find meaning in their cancer experiences and how current treatments could be adapted for pediatric palliative care and end-of-life decision-making.

I am a member of the American Psychological Association, American Psychosocial Oncology Society, and the Association of Psychologists in Academic Health Centers.

I am continually inspired and humbled by my patients and their families. In many ways, cancer becomes an indelible aspect of a patient’s and family’s life. Part of my responsibility is to help patients and their families build the confidence to tell their own stories, to embrace the unknowns of treatment, and to identify their new normal.
