Built on Good Medicine, Not Instead of It

Integrative and functional medicine works best when it is built on a foundation of sound conventional care. Dr. Kim works alongside your existing physicians and specialists — your primary care doctor, your endocrinologist, your oncologist — not as a replacement for them. If a specialist has prescribed a treatment your body genuinely needs, his role is to help you thrive on top of that foundation, not to offer an alternative to it.

If you are looking for a practitioner to substitute for medically necessary care, this practice will not be a good fit — and we would rather you know that before you book.
