Why functional medicine works
Conventional medicine is brilliant at naming and treating disease. Functional medicine asks a different question first: why is this happening? It looks at the whole system — nutrition, hormones, gut, sleep, stress, genetics — to find and address the underlying drivers.
At Next Level, functional medicine is never “instead of” good conventional care — it’s layered on top of it. Dr. Sheeler has served as a consultant to the Institute for Functional Medicine, and both physicians are IFM-certified.
- Root-cause investigation, not symptom suppression
- Advanced biomarker and genomic testing
- Nutrition & lifestyle as the foundation
- Pharmaceuticals and natural medicine, by your choice

Functional Medicine FAQs
At Next Level, yes. Our physicians are Mayo Clinic-trained and board-certified in conventional medicine, and apply functional approaches as a science-driven layer on that foundation — not a replacement for it.
Regular care often manages symptoms; functional medicine invests time to find the underlying cause — using advanced testing, genomics and a systems view of how your body works together.
Commonly: thyroid disease, metabolic and blood-sugar issues, gut/IBS, fatigue, hormone imbalance, and sleep — though the approach applies broadly. We tailor it to your goals.
