HARRISBURG (AP) - Pennsylvania’s acting health secretary will resign her post and depart the Wolf administration at the end of December, the governor’s office announced Monday.

Alison Beam had served in an acting role since January, when Democratic Gov. Tom Wolf tapped her to replace Dr. Rachel Levine, who left for the Biden administration.

“I am proud to have worked with Acting Secretary Beam over the past several years, and the commonwealth has been fortunate to have had the benefit of her leadership during the COVID-19 pandemic - especially as the Department of Health oversaw a massive vaccine rollout over the course of the past year,” Wolf said.

Beam, who had previously served as Wolf’s deputy chief of staff, guided the state’s COVID-19 pandemic response over the past year. She oversaw vaccine distribution and imposed a mask mandate for schools that was struck down by the Pennsylvania Supreme Court last week.

Keara Klinepeter, the Health Department’s executive deputy secretary, will take over as acting secretary, Wolf said.

“I look forward to continuing to work closely with the tremendous employees at the Department of Health and ensuring public health remains a top priority throughout the commonwealth,” Klinepeter said.

The administration did not give a reason for Beam’s resignation.

Wolf is heading into the last year of his governorship.
