Hi, I'm Dr. William Yu, a board-certified psychiatrist with over 15 years of experience providing medication management and psychotherapy for adults and adolescents. My areas of expertise include depression, anxiety, ADHD, trauma-related conditions, and life transitions.

If you are feeling overwhelmed by anxiety, stuck in patterns of trauma, or exhausted by PTSD, healing is within reach. I am a compassionate psychiatrist whose practice is informed by a social-work lens. This means I look at the big picture—how social, environmental, and biological factors impact your mental health. My goal is to guide you from a place of survival to thriving. I provide careful diagnostic assessments and tailored treatment plans that respect your preferences, helping you safely process the past and reclaim control over your future wellbeing.

I am a triple board‐certified Family Nurse Practitioner (FNP), Certified Nurse Midwife (CNM), and Psychiatric Mental Health Nurse Practitioner (PMHNP). This unique combination allows me to care for individuals across the entire lifespan, with a deep understanding of how physical health, hormones, trauma, environment, and life transitions shape mental well‐being.

My approach is collaborative, integrative, and rooted in both conventional psychiatry and functional medicine principles. I work to understand the root causes of symptoms—not just treat them—by considering biological, psychological, hormonal, nutritional, and environmental factors. Treatment plans may include medication management, lifestyle strategies, mind‐body approaches, and supportive therapy.

My style is warm, patient‐centered, and grounded in partnership. We build your plan together, ensuring it is evidence‐based, individualized, and flexible as you grow. Whether you’re navigating anxiety, depression, trauma, mood changes, or complex mind‐body concerns, my goal is to meet you where you are and support you toward lasting emotional and physical wellness.
