TORCHBEARERS FOR BETTER HEALTH
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.
A FORCE MULTIPLIER
The OurHealth difference
OurHealth merged with Marathon Health in 2020 to deliver the most comprehensive product on the market. OurHealth’s MyClinic Network is the first and only access point to deliver advanced primary care where people live, work and shop. Preventive and acute visits, behavioral health, onsite medications and more than 1,500 lab services within a 10-minute drive led to higher engagement among employees and dependents and continues to be the driving force of our growth.
COAST-TO-COAST CARE
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.
THE INDUSTRY LEADER
Improving lives
is rewarding
When healthcare gets more immediate, engaging, and personal, costs go down, outcomes improve, and everyone wins.
