Serving those who deserve it most

Every day more than 10,000 people in the United States become eligible for Medicare. That’s 10,000 parents, grandparents, aunts, brothers, friends and mentors who deserve a better, simpler and more empathetic healthcare system.

Our opportunity

More than 25% of these seniors live in rural communities where access is a challenge—smaller hospitals are closing or consolidating, specialists are often long distances away and primary care providers are retiring rapidly. Virtual care, while valuable, remains limited by broadband access and does not replace the benefits of trusted local care.

Rural communities also tend to have lower Medicare Advantage participation levels, which means fewer benefits for these patients. Studies show that seniors living in rural communities experience:


higher prevalence of multiple chronic conditions


higher prevalence of diabetes


higher prevalence of obesity


higher prevalence of chronic heart failure


higher mortality rate

Oasis is here to address these disparities and reimagine rural senior care.

Meet Our CEO

Brian Mathis

Meet Brian Mathis, co-founder and chief executive officer of Oasis Health Partners. Prior to Oasis, Brian served as chief strategy officer at Sevita, the largest provider of home and community-based healthcare in the U.S., and Optum Care, the country’s largest risk bearing physician organization. In these roles, Brian had the opportunity to help build an integrated care offering for people with intellectual and developmental disabilities and enable thousands of physicians to advance in value-based care. He saw firsthand some of the most striking challenges to achieving health equity in this country, most of which tie directly to access to great preventative care. Brian believes there are heroes in communities across America making this possible every day for some and is eager to help more people access the care they deserve.

Meet Our President

Kari Severson Snaza

Meet Kari Severson Snaza, co-founder and president of Oasis Health Partners. Kari’s family roots are proudly planted in rural communities across the Midwest. Growing up, she saw the vast inequities in care between small towns and big cities. These formative personal experiences inspired her to devote her career to healthcare. Throughout her career, Kari has had the opportunity to work in value-based primary care with health systems and health plans across the U.S. and abroad. Most recently, she served as the chief strategy officer for Mayo Clinic, following a fifteen-year career at UnitedHealth Group. Her journey has taught her what great care looks like and what opportunities remain. Looking forward, Kari is motivated to make healthcare more resilient, patient-centered and sustainable.
