Wisniewski has been in the city's CDO for more than four years. His departure comes as the city looks to restructure the Office of Open Data and Digital Transformation.
Tim Wisniewski, who has served as Philadelphia's chief data officer for more than four years, is stepping down at the beginning of January, according to a press release from the mayor's office.
Wisniewski's departure comes as the city looks to reorganize the Office of Open Data and Digital Transformation, which he led. The open data team will now become part of the Office of Innovation and Technology, led by Chief Innovation Officer Mark Wheeler. The rest of ODDT will continue reporting to Chief Administrative Officer Christine Derenick-Lopez.
The CDO has no plans for what he will do next, according to the report. Liana Dragoman, ODDT's deputy director, will lead the office in an interim capacity.
Editor's note: This story has been corrected to show that only the open data team is moving to OIT.
