About Dr. Mitchell

Dr. Sarah Mitchell is a board-certified internal medicine physician and IFM Certified Practitioner with over 12 years of experience in functional and integrative medicine. After watching conventional medicine fail her own mother with Hashimoto's, she trained at the Institute for Functional Medicine and built her practice around root-cause investigation.

She specializes in autoimmune thyroid disease, hormone imbalance, and chronic fatigue — the exact conditions conventional medicine consistently dismisses as "normal labs, nothing wrong." Her practice runs deeper panels, looks for triggers most doctors don't test for, and builds personalized treatment plans that actually move the needle.

Treatment approach

Every new patient starts with a 90-minute intake — long enough to actually understand the timeline of your symptoms. From there, Dr. Mitchell typically orders:

  • Comprehensive thyroid panel (TSH, Free T3, Free T4, Reverse T3, TPO/Tg antibodies)
  • Full hormone panel (cycle-dependent for women)
  • Gut health markers + stool testing when indicated
  • Comprehensive micronutrient panel
  • Inflammatory markers and food sensitivity testing

Treatment plans combine targeted nutrition (often AIP or modified elimination), bioidentical hormones where appropriate, gut healing protocols, and stress/HPA-axis support. Most patients see meaningful improvement within 3–6 months.

"Four conventional doctors told me my labs were normal and I just needed to sleep more. Dr. Mitchell ran a real thyroid panel — TPO antibodies were 380. We're treating Hashimoto's now. My fatigue is gone for the first time in 6 years."

"The 90-minute intake was the first time a doctor actually listened to my full health timeline. She caught a gut issue I'd been ignoring for years. Bonus: telehealth means I didn't have to drive 3 hours each appointment."

Treated for: Autoimmune + Gut Health
