Sponsored by the Institute for Functional Nursing. Learn more about our programs at www.fxnursing.com Functional psychiatry is one of the least common niches in the functional medicine world, but it is often where patients experience some of the most profound “whole person” care. In this episode, Brigitte Sager interviews Everest Goldstein, board-certified psychiatric nurse practitioner and IFM certified clinician, about what functional psychiatry really means, how she built her practice, and why nursing is uniquely positioned to lead in this space. Everest shares her own turning point after Lyme disease, when a provider spent the time to take a full functional history and connect the dots. From there, she explains how functional psychiatry treats depression and anxiety as symptoms with root causes, not labels that end the conversation. You’ll hear practical, surprising examples of how gut health, cortisol dysregulation, dysbiosis, H. pylori, constipation, and yeast overgrowth can drive mood symptoms, and why foundations like sleep, stress, movement, and nutrition matter more than “shiny objects” like endless supplements, peptides, or IVs. They also discuss building community as a clinician, the realities of starting a practice, and how nurses can confidently work within scope by focusing on foundational health behaviors and patient education.

Key Takeaways Functional psychiatry is a root-cause approach that integrates conventional and functional tools to restore whole-person health Depression and anxiety can reflect underlying physiology such as gut dysfunction, cortisol patterns, hormones, sleep disruption, or unresolved trauma Gut health is a recurring driver in mental health cases, including dysbiosis, H. pylori, constipation, and yeast overgrowth “Treatment-resistant depression” often signals an incomplete root-cause workup, not a lack of options Many medication side effects and poor responses make more sense when you evaluate stress physiology (including low cortisol patterns) Nurses can create major impact within scope by prioritizing foundations: nutrition, sleep, movement, stress regulation, and lifestyle change support New functional providers often overuse supplements; experienced clinicians typically simplify and return to the basics Sustainable practice building requires boundaries, community, and a clear niche that patients can understand Featured Guest Everest Goldstein, PMHNP-BC, IFMCP Founder, Everest Functional Psychiatry and Wellness, and Evergreen Functional Collective Facebook Instagram
