About Us

The Oklahoma Blood Institute, Arkansas Blood Institute, Texas Blood Institute, and Coffee Memorial Blood Center – collectively are the sixth-largest non-profit blood collector in the nation. No matter the location, we provide the donor-to-patient lifeline in our local communities. We are Our Blood Institute.

Our Blood Institute is the sixth-largest non-profit blood collector in the nation, providing more than 90% of the state’s blood to over 160 hospitals, medical facilities, and air ambulances spanning across Oklahoma, Texas, & Arkansas.

In recent years, blood centers in Texas and Arkansas joined the OBI system, ensuring hospital partners in those areas have access to a reliable, sustained blood supply. In Arkansas, the Arkansas Blood Institute provides blood for patients in more than 40 hospitals statewide. In Texas, Coffee Memorial Blood Center provides blood for patients across the High Plains region, and Texas Blood Institute provides for all major hospitals in the Texoma region.

Innovation & Research

As medicine and the needs of patients evolve, so do we. We advance the science of blood banking by conducting research, developing innovative technology solutions and connecting potential research subjects with studies available in their area.
