Why we're different
Care built around you
Every plan is individualized
No two patients get the same plan. Your history, your labs, and your goals shape it.
Lyme-literate and ILADS-informed
Deep experience with Lyme, tick-borne illness, and complex chronic cases.
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. Our Lyme care is guided by the International Lyme and Associated Diseases Society (ILADS), and complex Lyme is a big part of what we do.
- 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.
