We care for people with complex, chronic health concerns, including Lyme and tick-borne illness, mold-related illness, long COVID, and autoimmune conditions that may not tell the whole story.

We also work with people who feel well and want to better understand their health, improve how they feel, and stay well for the long term.

Our approach brings a wide range of integrative and functional medicine options together in one practice, including bioidentical hormone replacement therapy (BHRT), peptide therapy, IV therapy, Weber Endolaser therapy, homeopathy, and more.

Why we're different

Care built around you

Every plan is individualized

No two patients get the same protocol. Your history, your labs, and your goals shape the plan.

Lyme-literate and ILADS-informed

Deep experience with Lyme, tick-borne illness, and the complex chronic cases other clinics send our way.

We look for the root cause

The goal is to understand why you feel the way you do, not just to quiet the symptoms.

A big part of what we do

Lyme and tick-borne illness

If you have been exhausted, foggy, and aching for years, bounced between specialists, and told your labs look normal, you are not imagining it. Lyme and its coinfections are easy to miss and hard to treat. We are a Lyme-literate, ILADS-informed practice, and complex Lyme is exactly the kind of case other clinics send our way.

  • Fatigue that rest does not fix
  • Brain fog, memory trouble, word-finding struggles
  • Joint and muscle pain that moves around
  • Headaches, nerve tingling, or burning
  • Unrefreshing sleep and symptoms that flare in cycles

These symptoms can have many causes. Evaluation helps determine which possibilities deserve further investigation.
