Allan Frank, who as the city's chief technology officer worked to consolidate Philadelphia's information technology efforts, will stop working for the city in February.

Frank will return to private industry.

As the city's second-highest paid employee, he earned $209,000. The top earner is chief medical officer Sam Gulino, at $239,200.

Mayor Nutter also announced Wednesday that Frank will serve as chair of a new advisory body, the Mayor's Advisory Board on Technology.

"Allan has played a vital role in restructuring the City's IT assets," Nutter said.

Tommy Jones, the first Deputy Chief Information Officer, will serve as interim Chief Technology Officer while the city begins a nationwide search for Frank's successor.

Frank did not return a call seeking comment.

He was the city's first Chief Technology Officer and led an effort to consolidate all information technology assets, people, operations and financial resources in one division. Previously, that work was spread across 33 city agencies.

Frank also played a key role for the city and several nonprofits in winning $18 million of federal broadband stimulus funding to support computer centers, training programs and jobs that serve Philadelphia neighborhoods with limited broadband access, the city's press release said.
