A Practice Built on Principle
PreserveHealth was founded on a simple conviction: that exceptional medicine requires time, attention, and continuity. Our membership-based concierge nephrology practice in Newport Beach brings together board-certified kidney specialists and internal medicine physicians who serve a limited number of patients across Orange County — ensuring that every appointment is unhurried, every decision is evidence-based, and every patient has direct access to their physician. We do not manage volume. We manage complexity.
Our Founding Physicians
PreserveHealth was founded by a group of board-certified specialists with decades of combined experience in nephrology, internal medicine, and complex chronic disease.

01
Direct Physician Access
Your physician is reachable — not a portal, not a nurse line. Membership means a direct relationship with the doctor managing your care.
02
Unhurried Appointments
We see fewer patients by design. Every appointment is allocated the time your condition requires — not the time a billing cycle permits.
03
Coordinated Complex Care
For patients navigating multiple specialists, hospitalizations, or transplant evaluations, we serve as the central clinical authority — ensuring nothing falls through the cracks.
MEMBERSHIP WITHOUT BORDERS
