About US-LTN

The national rural health utility.

US-LTN deploys cellular telemetry and community-based logistics to reverse chronic disease in rural America. We built the operating system for value-based care — and we run it ourselves, in the communities the healthcare system left behind.

Our non-profit mission

Care that answers to communities.

The mission of Rappahannock Health Corporation is to empower underserved communities through comprehensive disease education, the facilitation of local wellness programs, and the promotion of public health awareness to help individuals build sustainable, healthier lives.

US-LTN — the United States Local Triage Network — is how we carry that mission into rural homes: daily health monitoring, lifestyle medicine, and local clinical teams for the communities the healthcare system left behind.

Our clinical services — home health monitoring, cellular telemetry, and lifestyle-medicine programs — are delivered in furtherance of this charitable mission, not for private profit. Program revenue, including Medicare reimbursements, is reinvested in patient monitoring equipment, local clinical staffing, and community wellness and education programs.
