Stephen Evangelista Appointed Social Security’s Deputy Commissioner for Operations

The Social Security Administration (SSA) today announced the appointment of Stephen Evangelista as the Deputy Commissioner for the Office of Operations. In this role, he will oversee SSA’s nationwide network of offices that provide frontline and support services to millions of customers each year. This includes oversight of more than 1,200 field offices serving communities across the country, as well as 23 teleservice centers assisting the public on the phone.

Stephen Evangelista has over 25 years of experience in executive leadership roles at SSA. He has held various leadership positions within the agency, most recently serving as the Assistant Deputy Commissioner for Policy in the Office of Law and Policy. His record of achievement includes developing and implementing an enterprise strategy to unify SSA’s more than 3,000 data matching agreements, resulting in improved program administration.

"Stephen's proven track record of leadership and his dedication to public service make him an excellent choice for this critical role," said Lee Dudek, Acting Commissioner of Social Security. "His deep knowledge of the agency’s programs will be an asset as we continue to improve customer service while safeguarding Americans’ hard-earned benefits."

Stephen Evangelista succeeds Doris Diaz, who had been serving as the agency’s Acting Deputy Commissioner for the Office of Operations since January 2025. Under her leadership, SSA implemented several customer-focused improvements, including expediting over $14.8 billion in retroactive payments to more than 2.2 million individuals under the Social Security Fairness Act.

“I am grateful to Doris for her outstanding leadership of the Office of Operations,” added Dudek. “She delivered transformational improvements in the agency’s operations, and millions of Americans’ lives are better because of her service.”
