Aaron-Thomason-Functional-PsychiatryMeet Aaron Thomason — Integrative Psychiatric Nurse Practitioner

Aaron is a dual board-certified Family and Psychiatric Mental Health Nurse Practitioner with over 15 years of diverse clinical experience. From family medicine and urgent care to cardiothoracic surgery and psychiatric care, Aaron brings a rich, whole-person perspective to healing.

He’s spent the past five years focusing exclusively on mental health, where he combines deep clinical expertise with a compassionate, down-to-earth approach. Aaron believes mental wellness is not just about symptom relief—it’s about helping each person return to balance, clarity, and vitality through integrative, patient-led care.

Why ICIM?

Aaron joined the Idaho Center for Integrative Medicine (ICIM) to be part of a team that shares his belief in treating the root cause of illness, not just managing symptoms. ICIM’s model allows Aaron to offer truly holistic psychiatry, integrating advanced lab testing, hormone evaluation, nutrition, and lifestyle-based interventions alongside conventional treatment options.

Here, he can support clients with:

  • Hormone testing and balancing (especially cortisol, thyroid, sex hormones)

  • Functional lab analysis to identify underlying drivers of mental health symptoms

  • Nutritional psychiatry: using diet and targeted supplementation to support brain function

  • Lifestyle optimization: improving sleep, movement, relationships, and spiritual health

  • Medication management when appropriate, with an emphasis on minimal effective use and long-term healing

A Philosophy of Whole-Person Healing

Aaron’s care philosophy is deeply shaped by his own life experiences, faith, and the belief that every person has the capacity to heal when given the right tools and support. His father’s words—“leave every place better than you found it”—are the foundation of how he approaches each patient relationship.

At ICIM, Aaron offers a space where you can feel safe, heard, and empowered to participate in your healing journey. Whether you’re navigating anxiety, depression, trauma, burnout, or hormonal imbalances affecting mental health, Aaron partners with you to create a clear, personalized path forward.

Outside the Office

A lifelong Idahoan, Aaron enjoys mountain biking, backpacking, and time with his wife and four daughters. He’s active in his church and volunteers regularly on mission trips to Guatemala—living out his calling to serve and uplift others.

Rediscover Balance. Reclaim Your Life.

At ICIM, we believe that mental health is more than the absence of illness—it’s the presence of peace, resilience, and purpose. Aaron is here to walk with you every step of the way—combining the best of modern psychiatry with the depth of functional and integrative medicine.
