Healthcare
as it
should be.

Thoughtful medicine.
Real relationships.
Care built around you.

Andersonville Internal Medicine is a Chicago-based concierge internal medicine practice providing personalized primary care for adults through a relationship-centered, membership-based model. By caring for a smaller patient panel, our board-certified internal medicine physicians are able to offer extended appointments, proactive preventive care, and direct access. We create the time and space for meaningful conversations and informed decision-making. Patients receive 24/7 access to their physician, same-day or next-day appointments, and regular health check-ins focused on both chronic disease management and long-term wellness. Our concierge care model emphasizes coordinated care, close collaboration with specialists, and active patient advocacy, so your healthcare feels seamless, personal, and consistent over time.

Access When You Need It

Clock icon

With a significantly smaller physician-to-patient ratio, we’re able to offer same-day or next-day appointments for most needs, along with direct, ongoing communication through multiple channels. You can reach your physician quickly in an emergency. This level of access allows concerns to be addressed promptly, decisions to be made more thoughtfully, and care to move at a pace that reflects real life.

A Dedicated Partner


​​Membership means having a physician who knows your history, understands your priorities, and stays closely involved in your care over time. That continuity matters in every stage of health, but it becomes especially important when managing ongoing conditions or navigating new diagnoses.

With more time and regular engagement, care can shift from reactive to proactive. Membership allows us to focus on prevention early, developing personalized wellness plans, addressing risk factors, and supporting lifestyle changes that reduce health risks over time.

Our physicians guide care thoughtfully, collaborate closely with specialists, and advocate on your behalf, so you’re never navigating the healthcare system alone.

Evolving Personal Care


Your health goals aren’t static, and neither is your care. Membership allows for personalized health planning that adapts as your needs change. Through regular check-ins and ongoing communication, we work together to refine goals, adjust strategies, and keep care aligned with your life, not just your chart.

Education is central to this process. We take the time to explain diagnoses, options, and recommendations clearly and thoughtfully. Our patients feel informed and are more confident and engaged in their care.
