About
Dr. Sarah Solinger, PhD, ND, MSc, FCN
Founder of Root Health L.L.C. and The Solinger Method
Dr. Solinger is a U.S. Army veteran and multi-doctoral clinician whose work integrates over a decade of advanced training, clinical practice, and complex case analysis. Her background spans naturopathic medicine, clinical nutrition, psychology, systems physiology, and root-cause pattern recognition.
She is the founder of Root Health L.L.C. and the creator of The Solinger Method, a functional wellness system designed to help individuals understand the physiologic patterns driving symptoms rather than chasing diagnoses or isolated lab values. Her work focuses on clarity, structure, and biologic logic, translating complex physiology into practical, actionable understanding.
Over the past decade, Dr. Solinger has worked extensively with complex and multi-system presentations, reviewing thousands of functional laboratory reports and identifying recurring patterns across gastrointestinal, endocrine, metabolic, micronutrient, mitochondrial, neurological, and immune pathways. Her experience includes case-based consulting, physiologic mapping, and pattern analysis for individuals with chronic illness, metabolic instability, hormonal shifts, trauma-related physiologic disruption, unexplained fatigue, and conditions often overlooked or minimized in conventional models.
Her clinical approach is deeply shaped by her military background. The discipline, structure, and strategic thinking developed during her service as a U.S. Army veteran inform her methodical, pattern-driven approach to human physiology and health restoration.
Dr. Solinger’s philosophy is straightforward: chronic symptoms are not random. They follow predictable physiologic sequences long before disease is diagnosed. When those patterns are understood, intervention becomes clearer, more targeted, and more effective.
The Solinger Method exists because the modern health system often leaves individuals with “normal labs,” unanswered questions, and persistent symptoms. By integrating physiology, micronutrients, psychology, and system-to-system communication, Dr. Solinger provides a framework for understanding what is actually happening in the body and how to support it intelligently.
Her work is evidence-informed, clinically practical, and grounded in real-world application. At its core, it is designed to restore clarity, confidence, and direction for those who have been left guessing about their health.
This is where clarity begins.
