Rochester, N.Y., CIO David Mayor submitted a letter of resignation last week as he prepares to take a new position as CIO of the Minneapolis Public School District.

Mayor took Rochester’s technology helm in September 2008. During his tenure, he oversaw the implementation of a new customer relationship management system to assist with citizen outreach campaigns, the launching of the city’s new official website, and enhancements to a system that supports the sale of tax liens.

Other achievements Mayor oversaw include a program to integrate and automate the city’s business processes and transactions, an improved database for crime analysis and the launch of video surveillance cameras in areas prone to higher crime rates.

“Under David Mayor’s leadership, the Department of Information Technology has taken this administration to a new level of innovation, giving us the tools we need to improve customer service and government transparency while reducing the cost of operations,” said Rochester Mayor Thomas Richards, in a statement.

Mayor’s resignation will go into effect as of Dec. 31, and his new position in Minneapolis will start Jan. 1, 2012. According to a Rochester announcement, Richards has already started a broad search to fill the soon-to-be vacant CIO position.
