Susan Earl, ACNP-BC, is a 2026 Distinguished Health Professional (Collierville) with over 40 years of medical experience. As the founder of The Fatigue Clinic, she combines a deep background in emergency medicine and cardiology with advanced certifications in functional and holistic medicine. Susan is the longest-certified functional medicine provider in the Collierville-Germantown-Eads area, specializing in root-cause treatments for autoimmune, cardiovascular, and complex chronic conditions. For 16 years, she has led The Fatigue Clinic in providing individualized care to patients in Collierville, Germantown, Memphis, and Arlington who seek natural and biology-based solutions for their health.
For decades, the standard medical model has focused heavily on acute care and symptom suppression. This traditional approach is essential for emergencies but often fails patients with chronic, complex illnesses. Over the last forty years, a significant shift has occurred as more providers recognize the need for Functional Medicine (a biology-based approach that identifies and addresses the root causes of disease). This evolution in healthcare moves away from the "pill for every ill" mentality and toward a deep understanding of how genetics, environment, and lifestyle interact.
Susan Earl began her medical journey in high-stakes environments. With a background as an Acute Care Nurse Practitioner (ACNP-BC), she spent years on the front lines of Emergency Medicine and Cardiology. This experience provided her with a rigorous understanding of human physiology and the critical nature of systemic health. In emergency settings, the focus is on immediate stabilization. In cardiology, the focus is on the body’s most vital pump.
These 40 years of experience allow Susan to bridge the gap between conventional medical necessity and holistic wellness. She understands the life-saving power of modern medicine while recognizing where it leaves gaps for chronic sufferers. Her transition into holistic medicine was driven by a desire to help patients achieve more than just "not being sick." She wanted to help them thrive by investigating why their systems were failing in the first place.
Experience matters when dealing with complex system problems. Susan Earl is recognized as the longest-certified functional medicine provider in the Collierville, Germantown, and Eads area. This distinction is not just a title; it represents decades of continuing education and clinical application of root-cause principles. In 2026, she was named a Distinguished Health Professional in Collierville, further cementing her status as a leader in the local medical community.
When searching for a holistic doctor Memphis TN, patients often find themselves overwhelmed by new clinics. However, Susan’s 16-year tenure at The Fatigue Clinic provides a level of stability and proven results that is rare in the industry. She has spent nearly two decades refining protocols for autoimmune disorders, neurological issues, and complex chronic fatigue. Her longevity in the field ensures that patients receive care based on both historical medical wisdom and the latest scientific advancements.
Functional Medicine is defined as an integrative, science-based healthcare approach that treats the whole person, not just an isolated set of symptoms. At The Fatigue Clinic, this means looking at the "soil" of the body: the gut microbiome, hormone balance, and cellular function: rather than just the "leaves" or the symptoms.
Susan’s approach is strictly biology-based. She utilizes advanced lab tests to look for markers that traditional blood work might miss. This includes testing for food sensitivities, heavy metal toxicity, and hidden infections. By identifying these triggers, she can create a personalized roadmap for healing that is unique to every patient. Call 901-221-8621 to schedule your initial functional medicine consultation.
