Centene provides health care insurance to more than 12.3 million government-assisted and low-income beneficiaries. Since joining the company, Mason has spearheaded the development of many clinical programs aiming to strengthen health outcomes for pregnant women, patients with opioid dependence, and other diseases. “Start Smart for Your Baby” significantly increased birth weights and decreased premature births.
