Oklahoma Blood Institute (OBI) is the ninth largest, non profit blood center in America. Employing nearly 700 Oklahomans,  working with 1,000 volunteers and 2,600 blood drive coordinators, offering a variety of services to the community, and ensuring that every drop of blood donated is delivered to Oklahoma patients in more than 140 medical facilities, OBI has proven to be a valuable asset towards Oklahomans' well-being and general health.

Consequently, since 2011, ACT has partnered with OBI to host blood drives on the National Day of Reason and has heretofore donated over 65 units of blood.
