Emily E. Masi, Nurse Practitioner
Emily Masi, PMHNP, helps children, teens, adults, and seniors across California access compassionate, high-quality psychiatric care designed to support their stability, resilience, and overall well-being. She provides medication management with a warm, attentive, and highly personalized approach, helping patients navigate conditions such as anxiety, depression, ADHD, and trauma-related symptoms. Serving communities throughout California, she partners closely with individuals and families to create treatment plans that feel both clinically effective and deeply supportive.
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 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.
Outside of her clinical work, Emily enjoys exploring new places with her family—from quick weekend getaways around Los Angeles to international travel. She stays actively involved in her community through her book club, volunteer work at her children’s school, youth sports, and local event planning. Her home life is rooted in faith, cultural connection, and shared traditions, and she loves celebrating her family’s Hawaiian and Italian heritage through food, stories, and dance.
