What Chronic Disease Means for Your Care
A chronic disease lasts three months or longer and tends to linger, return or progress. Many patients reach us after years of treating each symptom with its own prescription.
We ask a different question: what imbalance, infection, deficiency or toxic load keeps your body from healing? Dr. Yosef focuses on that question for illnesses that are hard to pin down.

Chronic Disease Questions, Answered
What should I do if I have a chronic illness?
Look for what is driving it, not only a name for it. See a clinician who reviews your whole history and tests for causes such as infections, deficiencies or toxic exposure.
Why are some chronic illnesses so hard to diagnose?
Chronic fatigue syndrome, Lyme disease and mold illness share symptoms with many conditions, and routine blood work can look normal. That is why we add specialized testing and a full history review to standard labs.

Yes. Dr. Yosef treats elusive illnesses including Lyme disease, and Lina Kay, PA-C, MS, focuses on environmental medicine, including mold illness.
How much does chronic disease care cost?
