How should nurses list credentials after their name? In this episode of the Functional Nurse Podcast, Dr. Brigitte Sager explains how nurses, nurse practitioners, and advanced practice nurses can understand and display their professional credentials with more clarity and confidence.

If you have ever wondered whether RN, BSN, MSN, DNP, APRN, NP, board certification, holistic nursing certification, or your other credentials should come first, this episode will help you make sense of the “alphabet soup” after a nurse’s name. Brigitte breaks down the difference between academic degrees, nursing licensure, advanced practice titles, national board certifications, specialty certifications, and program-created certificates.

You’ll also hear how credentialing applies to nurses entering functional, holistic, and integrative healthcare. Brigitte discusses holistic nursing board certification through AHNCC, the Institute for Functional Medicine’s certification process, and the future need for a true functional nursing board certification.

This episode is especially helpful for RNs, NPs, APRNs, nurse entrepreneurs, holistic nurses, functional medicine nurses, integrative health professionals, and nurses pursuing advanced education or specialty training. Whether you are updating your email signature, website bio, resume, professional title, or social media profile, this conversation will help you think more carefully about credibility, professionalism, and how to represent your qualifications accurately.

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.

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
