Emily is especially passionate about women’s mental health and reproductive psychiatry, including care related to puberty, perinatal and postpartum challenges, hormonal transitions, menopause, and reproductive stressors. She also brings strong expertise in supporting individuals experiencing later-life transitions, grief, and insomnia. Her work centers on helping patients understand the biological, emotional, and environmental factors shaping their symptoms so they can regain a sense of control and confidence in daily life.
In addition to her core focus areas, Emily offers medical procedure evaluations and psychological testing, along with Christian counseling for those who wish to integrate faith into treatment.
She has extensive experience supporting autism spectrum disorders, developmental disabilities, and first responders and military veterans, and she provides care for additional populations with unique and diverse needs. She also assists with workers’ compensation and disability-related documentation as part of comprehensive patient support.
