At Los Altos MD, medicine is more than healthcare—it’s a deeply personal experience. What began as Dr. John Madej’s solo internal medicine practice has evolved into a private practice where medical expertise meets genuine connection, and every patient is cared for like a member of our extended family.

With decades of trusted care behind him, Dr. Madej now partners with his daughter, Dr. Jessica Madej, blending the wisdom of experience with the fresh insight of a new generation. Together, they provide a level of access and attention that’s rare in today’s healthcare—longer visits, unhurried conversations, and a truly personalized plan for your health and wellness.

Our concierge-style approach is built on the belief that meaningful relationships are at the heart of exceptional care. As a father-daughter team, we provide continuity, trust, and open communication, caring for you through the entire journey from clinic visits to hospital care and ensuring you are supported every step of the way.

From preventive care to complex medical needs we are here to guide you with skill and compassion.

Welcome to Los Altos MD—where your health is our family’s priority.
