Office of the Chief Integrity Officer

Promoting integrity, transparency, and accountability throughout the executive branch of government.

Office of the Chief Integrity Officer

What we do

Philadelphians deserve a government that works well, is honest and fair, and uses taxpayer dollars effectively. The Office of the Chief Integrity Officer (CIO) promotes these values by:

  • Providing education about the City’s ethics rules to City employees and the public.
  • Developing policies to make sure the City operates responsibly and with integrity.
  • Improving access to City information.

While ethics rules may change to reflect advances in technology or best practices, maintaining a strong culture of ethics is a bedrock of the CIO and the mayor’s administration.
