Physician-founded. 
AI-powered.
Leading the future of primary care.

Lumeris is a physician-first healthcare transformation company based in St. Louis, Missouri, with more than 15 years of proven leadership in healthcare operations and value-based care enablement. 

Founded by doctors and guided by deep clinical, operational, and technical expertise, we help health systems and physician organizations deliver better outcomes, lower costs, and a better experience for patients and providers. 

Today, we’re combining our legacy of success with the power of AI to pioneer Primary Care as a Service (PCaaS)—expanding access, reducing burden, and making it easier for physicians to focus on what matters most: caring for people.

Healthy systems.
Healthy people.
Healthy outcomes.

Our purpose comes to life through three guiding principles—each focused on empowering physicians, enabling systems, and restoring the human side of healthcare.

Healthy systems.

Let systems serve.

Empowering primary care delivery for health systems

Now, Tom’s reach goes beyond value-based care models. It’s designed to work for every health system, every physician, and every patient — whether in Medicare Advantage, ACO REACH, commercial, or fee-for-service settings. It’s primary care that is:

Improving access and experience through responsible AI

We use AI to bridge the gap between visits—so doctors stay better connected to patients, and patients get more from their doctor and care team. Every patient deserves easier access to primary care, stronger continuity, and a better overall experience. Technology should bring care closer—not get in the way. Our platform acts as a bridge, not a barrier—keeping patients engaged between appointments, surfacing the right insights at the right time, and making in-person time more meaningful. The result: fewer gaps, more trust, and coordinated care that patients remember—and return to.

Beyond the visit

Continuous outreach and engagement between appointments keeps patients on track.

Easier to be a patient

Simplifies the experience with personalized nudges, reminders, and clear next steps.

Smarter access

Surfaces the right care, at the right time—without overburdening the system.

Stronger relationships

Preserves and enhances the doctor–patient connection with every interaction.
