Lumeris Partners with Google Cloud to Address the U.S. Primary Care Shortage
Unique collaboration brings the best of AI, cloud computing, primary care expertise and proven solutions to help solve one of healthcare's most intractable problems
ST. LOUIS, June 12, 2025 /PRNewswire/ -- Lumeris, a leader in healthcare technology and services, and Google Cloud today announced a partnership to improve access to high-quality primary care in the United States by building Lumeris' Tom™ platform on Google Cloud technology. The collaboration targets a growing gap, where annual demand for care exceeds 2.5 billion hours, but less than 500 million hours are available, according to Lumeris estimates.
'AI is transforming healthcare in new and profound ways, including expanding access to more people,' said Thomas Kurian, CEO, Google Cloud. 'By combining Google Cloud's AI capabilities with Lumeris' decades of primary care insight, we can provide doctors and nurses with the AI support and insights they need to help improve care for their patients.'
Built by Lumeris and powered by Google Cloud's AI models and infrastructure, Tom is the industry's most advanced AI-powered Primary Care as a Service™ solution, acting as a proactive care team member embedded directly in clinical workflows to autonomously execute best next actions that expand capacity, improve access and reduce administrative burdens in primary care.
'The human toll of the primary care shortage is staggering—missed diagnoses, delayed treatments, and inferior outcomes,' said John Doerr, chairman of Kleiner Perkins, and board member of Lumeris. " More than 100 million Americans lack access to primary care, and another 100 million are receiving suboptimal care. Now, two world-class companies — Google and Lumeris—are bringing their unique capabilities together to help solve this crisis. We have both the means and the resolve to dramatically improve care for hundreds of millions of Americans.'
Highlights of the Google Cloud and Lumeris partnership:
'Tom is designed to be the best partner and care team member a physician could ever have,' said Mike Long, chairman and CEO of Lumeris. 'Under the complete supervision of the physician, Tom is embedded in primary care workflows, autonomously executing the best next action with appropriate guardrails for each patient—performing hundreds of tasks from checking-in on patients, to scheduling screenings and monitoring medications, to conducting outreach and escalating issues. Healthcare delivery as we have known it for generations is now fundamentally changed forever.'
Lumeris working with Google Cloud and other partners means Tom's capabilities will remain current with the accelerating pace of AI innovation, ensuring Tom's users are deploying the most advanced, highest value Primary Care as a Service capabilities.
