Hilary Duvauchelle

Psychiatric Nurse Practitioner

About

Hilary Duvauchelle is a Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner with advanced training in functional medicine and more than 17 years of healthcare experience. She is passionate about supporting individuals across the lifespan, working with children, adolescents, adults, and older adults through a wide range of psychiatric and emotional challenges.

Hilary specializes in the treatment of anxiety, mood disorders, ADHD, autism spectrum disorders, eating disorders, and schizophrenia. She also provides compassionate support for women during the peripartum and postpartum periods, as well as throughout perimenopause and menopause, offering both medication management and supplement guidance while recognizing the complex relationship between hormones, mood, and executive functioning. Hilary proudly welcomes and supports members of the LGBTQ+ community, helping clients navigate questions of gender identity, authenticity, and self-understanding. Her work is deeply trauma-informed, helping individuals connect past experiences to present symptoms and identify meaningful paths forward.

Clients often express gratitude for finally finding a provider who truly listens, collaborates, and partners with them in their care. Although her training at Vanderbilt University is grounded in evidence-based medicine, Hilary approaches every client as a unique individual whose treatment should reflect their personal history, goals, and needs. Through a functional medicine lens, she seeks to uncover the root causes of symptoms while also prioritizing effective, timely relief.

Hilary’s passion for psychiatry emerged during her family medicine training, where she recognized the growing number of patients seeking mental health support through primary care. She observed that many individuals struggled to access specialized psychiatric services and were often left without adequate improvement. This experience inspired her not only to expand access to care, but also to practice a more holistic model of psychiatry—one that honors the whole person, including their past experiences, present circumstances, and future potential.

Whether someone is seeking psychiatric care for the first time or has spent years feeling frustrated and unheard, Hilary is committed to listening carefully, uncovering contributing factors, and developing an evolving treatment plan that supports both healing and self-discovery.

Approach

Hilary is deeply committed to her work and continually strives to provide thoughtful, individualized care for each patient. Drawing from her experience with a diverse range of clients, she remains dedicated to staying current with emerging research, innovative treatments, and evidence-based approaches to mental health care. Using principles of functional medicine, Hilary explores the underlying causes of symptoms by examining the connections between a client’s developmental history, environment, immune health, digestion, nervous system function, respiratory health, and emotional experiences. Her treatment approach may include support for nutrition, sleep, boundaries, thought patterns, medications, and supplements. Above all, she emphasizes meeting clients where they are and identifying realistic, sustainable starting points for change.

Hilary values collaborative care and works closely with providers both within and outside of Origins, including primary care physicians, therapists, and medical specialists. When appropriate, she also refers clients to additional specialists to ensure comprehensive support. She believes that integrating multiple treatment modalities creates continuity of care and allows clients to feel genuinely supported throughout their healing journey.

Training & Background

Hilary Duvauchelle earned her Master of Science in Nursing from Chamberlain University in Chicago, Illinois, with a focus on Family Nurse Practitioner training. She later completed a Post-Master’s Certificate as a Psychiatric Mental Health Nurse Practitioner at Vanderbilt University in Nashville, Tennessee. These dual certifications reflect her commitment to understanding both physical and psychological health in order to provide truly integrated care.

She also holds a Bachelor of Science in Nursing from Oregon Health & Science University in Portland, Oregon, and a Bachelor of Fine Arts from the University of Hartford in West Hartford, Connecticut.

Hilary completed her family medicine training within a federally qualified health clinic serving a broad and diverse population in the Portland metropolitan area. She has also worked with the largest mental health provider organization in the United States.

Between nursing school and nurse practitioner training, Hilary completed two years of functional medicine health coach training through the School of Applied Functional Medicine. There, she studied the root causes of both medical and psychological conditions and learned foundational approaches to supporting overall health and wellness.

Driven by curiosity and a passion for lifelong learning, Hilary continually explores innovative, evidence-based treatments that can support her clients on their mental health journeys. She holds dual national board certifications and is licensed in Oregon.
