Detroit Mayor Mike Duggan on Thursday announced a reorganization of some of the city's key leadership with appointments including planning director, chief public health officer and executive director for workforce development.

Following the exit of city Planning Director Maurice Cox, who is expected to become the planning commissioner of Chicago this fall, the city's chief of services and infrastructure Arthur Jemison will become group executive for planning, housing and development, the city said in a news release.

Duggan plans to nominate Jemison to assume the duties of the planning director as illustrated in the city's charter, which calls for confirmation by Detroit City Council.

In addition to planning, Jemison will manage the Housing and Revitalization Department, implementation of the Strategic Neighborhood Fund and Affordable Housing Leverage Fund and act as primary liaison to the Detroit Housing Commission and Detroit Land Bank Authority, the release said.

Infrastructure-related fields that were part of Jemison's portfolio, including the General Services Department, City Airport and coordination with agencies such as the Public Lighting Authority, have been given to COO Hakim Berry, city spokesman John Roach said in an email.

City departments that are involved with the demolition program, including the Buildings, Safety Engineering and Environmental Department and the Detroit Building Authority, have been added to new Chief Administrative Officer Bethany Melitz's portfolio, he said.

Melitz, who was director of the city's Lean Processing Team, will now oversee strategic planning for the city and work on cross-departmental projects such as the city's metrics and demolition.

Henry Ford Health System executive Denise Fair was named chief public health officer to lead the city's health department, including managing its public health programs as well as animal care and control, the city said in the release. Previously, Fair served as group practice director for Henry Ford Livonia, Novi and Southfield medical centers, according to her LinkedIn profile. She has more than a decade of experience overseeing a wide range of medical centers in the region.

Nicole Sherard-Freeman was named the city's executive director for workforce development. She previously served as president and CEO of the Detroit Employment Solutions Corp., the city's workforce development arm.

Sherard-Freeman is credited with helping oversee the transformation of city program Detroit at Work into a full-service employment agency. Through the program, more than 3,000 Detroit residents have received training in areas including skilled trades, health care, IT, logistics and hospitality.

DESC's chief financial officer Terri Weems will serve as president and CEO until a permanent replacement for Sherard-Freeman is found, the release said.

The vacancies were created recently when Health Officer Joneigh Khaldun, M.D., and workforce development director Jeff Donofrio took on leadership roles within Gov. Gretchen Whitmer's administration.

Other management changes include the addition of Sheilah Clay as director of training quality and retention at DESC. The newly created role will focus on outcomes of Detroit at Work career centers. She retired from the Neighborhood Service Organization in 2018, where she served as president and CEO for 18 years.

Dee Marx Prosi, who manages the Detroit at Work branding and promotion, will become director of marketing and outreach.

"We are fortunate to have a deep bench of talent within the administration to step into leadership roles when needed and have been successful in attracting outstanding new talent to our team," Duggan said in the release. "Each of these individuals brings outstanding track records and in their respective roles add a new dimension to our efforts to continually improve how we serve our residents."
