Lighting the way to healthcare that works better for all.
Marathon Health is on a path to become the most trusted health company by delivering outcomes that people care about.
We partner with employers to make healthcare work better for their employees. Powered by care that’s convenient and easy to access. That goes further, offering a fundamentally different experience focused on wellness before, during, and after a visit. That delivers lower costs, improved outcomes, and better health.
Community partner.
National footprint.
We take a strategic and flexible approach to our footprint driven by impact and need. Marathon Health operates health centers in over 40 states and we are the country’s only worksite health provider offering a network model.
Improving lives
is rewarding
When healthcare gets more immediate, engaging, and personal, costs go down, outcomes improve, and everyone wins.
That includes us—we’ve just been selected Best in KLAS for 2021—the only vendor in our category to ever have taken honor two years in a row.
