Lindsay Schiffhauer

M.S, CNS, Florida LDN

Telehealth based in St. Petersburg, Florida

I am a Board Certified Nutrition Specialist® (CNS) specializing in functional nutrition and nutrient-based interventions for complex chronic illnesses. My clinical practice focuses on identifying and addressing root drivers of inflammation, gut dysfunction, metabolic disturbances, and immune dysregulation through comprehensive nutrition assessment and personalized therapeutic dietary protocols.

I utilize extensive intake forms and initial consultations to evaluate each client's unique biochemical, genetic, lifestyle, and environmental factors. My approach integrates evidence-based nutrition science with functional health principles to support patients with autoimmune diseases, mast cell activation syndrome (MCAS), women's health conditions, and endocrine and metabolic disorders including thyroid dysfunction, insulin resistance, and hormonal imbalances.

I practice through a trauma-informed lens, recognizing the profound impact that stress, adverse experiences, and nervous system dysregulation can have on metabolic health, digestion, and nutrient utilization. I prioritize psychological safety, collaboration, and client agency in all clinical interactions, ensuring that dietary recommendations are realistic, sustainable, and respectful of each patient's lived experience and readiness for change.

I collaborate closely with each patient's healthcare team to ensure coordinated, integrated care. My practice is 100% virtual, allowing me to serve patients across multiple states while maintaining accessible, client-centered nutrition care.
