About Us

We have long been a proud example of The Oklahoma Standard in action. While we were founded in Oklahoma City more than 50 years ago and our headquarters remain here, our reach has extended to all corners of Oklahoma and parts of Arkansas and Texas over time.

Now, we are excited to announce that we are unified under one name and thrilled to call ourselves Our Blood Institute. This evolution allows us to join together all parts of our organization, creating an identity that truly embraces our mission. No matter the location, we provide the donor-to-patient lifeline in our local communities.

Our Blood Institute is the sixth-largest independent blood center in the nation, with 16 donor centers in Oklahoma, Arkansas and Texas. OBI is the nonprofit blood provider for patients at more than 240 hospitals, medical facilities, and air ambulances across all three states.

Our Blood Institute in Oklahoma: OBI has nine donor centers in Oklahoma and provides more than 90 percent of Oklahoma’s blood supply to more than 160 hospitals, medical facilities, and air ambulances.
