His new role places him in charge of handling public concerns, improving communication with residents, and strengthening how the county interacts with citizens on a daily basis.
The reshuffle also brings in Hibrahim Otieno as the new head of the environment docket.
Otieno previously served in the Medical Facilities department, and his move means he will now be responsible for issues such as waste management, sanitation, and environmental protection across the city.
This change is part of a wider restructuring involving ten chief officers, all done under the guidance of Section 45(5) of the County Government Act 2012, which allows the governor to reorganize staff for better service delivery.
Other changes include moving Godfrey Akumali from the Business and Hustler Opportunities docket to the Housing and Urban Renewal department.
His shift puts him at the centre of policies involving housing projects and urban development. Tony Michale Kimani, who previously led the Social Services sector, will now head the Social Services and Estate Management docket, expanding his responsibilities to include managing county estates and public welfare programs.
Another key adjustment sees Lydia Mathia transferred from Housing and Urban Renewal to the Business and Hustler Opportunities docket.
Her new role involves supporting small businesses, improving economic opportunities, and strengthening county initiatives targeting traders and young entrepreneurs.

At the same time, Sande Oyolo, who led Digital Economy and Startups, has been moved to the Medical Facilities docket, placing him in charge of managing health-related services and infrastructure.
The Digital Economy and Startups docket will now be overseen by Wilson Gakuya, who previously headed the Smart Nairobi sector. His experience in technology and innovation places him in a position to strengthen Nairobi’s digital transformation efforts.
Mache Waikenda has been shifted from Mobility to Mobility and AG ICT Infrastructure, giving him a broader mandate that connects transport services with digital infrastructure.
Clement Rapudo, who oversaw the City’s Culture, Arts and Tourism docket, has been moved to Smart Nairobi, while Zipporah Mwangi, formerly in Citizen Engagement and Customer Service, will now head the City Culture, Arts and Tourism docket.
Chief officers play an important role in running county departments. They manage daily operations, supervise staff, and make sure services are delivered efficiently.
They also help implement county policies and report directly to the County Executive Committee Members responsible for their departments.
These latest changes show a push to reorganize leadership in order to improve how county services are delivered to Nairobi residents.
