More than two months after the commissioner resigned, NY1 has learned the de Blasio adminsitration has selected a government veteran to lead the city's child welfare agency. He will have a tough fight ahead as the agency attempts to overcome the high profile deaths of several young children. This is a story you first saw on NY1.

David Hansell has a lot of experience in government.

"Would the city still be in a position to meet its legal obligation to provide access to shelter for people who are homeless or in imminent danger?" he asked in 2008.

He served in Washington and Albany, in the Bloomberg administration and under Rudy Giuliani.

And now NY1 has learned he will be heading up the city's beleaguered child welfare agency. The mayor is expected to make the announcement on Tuesday.

"We will be talking tomorrow about who our new commissioner will be and why," Mayor Bill de Blasio said on the Road to City Hall's Mondays with the Mayor segment.

Hansell is currently at the consulting firm KPMG where he specializes in social services.

Before that, he served in the Obama administration as an acting assistant secretary in the Department of Health and Human Services.

He was commissioner of the Office of Temporary and Disability Assistance under Governor Spitzer. During Giuliani's tenure, he worked on programs to tackle HIV.

"Many people in the transgender community also participate in sex work which could also expose them to HIV risks," Hansell told NY1 in 2001.

Hansell has a lot of experience in government for sure, penning a recent op-ed column in Governing magazine about modernizing the social services sector.

Still he has never been on the front lines of child protective work.

And he takes over an agency that has been under a cloud of scandal.

"I've known David Hansell for 15 years," said Sheila Harrigan, Executive Director New York Public Welfare Association. "He's very courageous and determined I think he knows how difficult this job is going to be."

That is because the previous commissioner, Gladys Carrion, resigned in December after several high profile deaths of children under ACS care.

At the time, she said she was leaving the office for her personal wellbeing.

At the end of her tenure, investigations found the agency suffered from high level, systemic issues. And the state appointed a monitor to review its child protective work.

"We have a lot of work to do to keep refining the system to keep protecting every child," Mayor de Blasio said. "This is work of reform that will never end."
