Concierge Medicine for Los Altos

Personalized Concierge Primary Care Near Los Altos.

Peninsula Doctor is a concierge medical practice in Menlo Park serving individuals and families in Los Altos and throughout Silicon Valley. Our approach to primary care is built around time, access, and a trusted relationship with a physician who truly knows you.

Our concierge primary care model limits each physician’s panel to just 100 patients. This allows for longer appointments, same-day care when needed, direct access to your physician, and a deeper understanding of your health, history, lifestyle, and long-term goals.

Comprehensive Primary Care, Prevention & Longevity.

Our care extends well beyond treating illness. We provide comprehensive primary care, preventive medicine, women’s health, and longevity care, with a strong focus on prevention, early detection, and healthy aging.

From comprehensive annual physicals and ongoing primary care to advanced diagnostics, women’s health, nutrition, and longevity medicine, many of your healthcare needs can be addressed within our practice. When specialty care is needed, we closely coordinate with leading specialists throughout Stanford, UCSF, Sutter Health, and the greater Bay Area.

Experienced Concierge Physicians Serving Los Altos.

Peninsula Doctor was founded by Dr. Ian Kroes, a Stanford-trained family physician who has practiced in Menlo Park for more than 20 years. Today, our physician team includes Dr. Ian Kroes, Dr. Judy Kim, and Dr. David Hiroshima—experienced family medicine physicians committed to highly personalized, relationship-based care.

Our physicians bring decades of combined experience, with training and backgrounds at leading institutions including Stanford, UCSF, and Sutter Health. That depth of experience allows us to manage a broad range of medical needs while keeping your care personal, connected, and comprehensive.

A Different Approach to Primary Care.

Choosing a concierge physician is about more than convenience. It is about having a doctor who has the time to understand your complete health picture and a medical team that can help you navigate your health over many years.

At Peninsula Doctor, our smaller patient panels allow us to be proactive rather than simply reactive. We take the time to understand your individual risks, priorities, and goals and develop a personalized approach designed to support both your health today and your quality of life in the years ahead.
