Nairobi Governor Johnson Sakaja has reshuffled his county executive team, reassigning outspoken Chief Officer for Environment Geoffrey Mosiria to the Citizen Engagement and Customer Service docket in a sweeping shake-up announced on November 18, 2025.
The changes, communicated through a circular signed by Sakaja, take effect immediately and affect at least ten Chief Officers across key county sectors.
According to the governor, the redeployments are routine and fall within his legal mandate under Section 45(5) of the County Government Act, 2012.
Mosiria, who has gained a reputation for his hard-hitting enforcement style and viral TikTok videos documenting crackdowns on polluters and non-compliant businesses, has been replaced by Hibram Otieno. Otieno previously headed the Medical Facilities docket.
Although Sakaja has downplayed the move as “normal reassignments,” sources at City Hall say Mosiria’s outspoken nature and high visibility had unsettled some county officials who felt he was overshadowing the governor. His no-nonsense enforcement campaigns drew both public praise and internal discomfort.
In the reshuffle, Acting County Secretary Godfrey Akumali was moved from the Business and Hustler Opportunities docket to Housing and Urban Renewal.
Lydia Mathia shifts from Housing and Urban Renewal to Business and Hustler Opportunity, while Sande Oyolo leaves Digital Economy and Start-Ups to take up Otieno’s former role in Medical Facilities.
Other key movements include Wilson Gakuya’s transfer from Smart Nairobi to Digital Economy and Start-Ups, and Dr. Machel Waikenda, who will now oversee ICT Infrastructure in an acting capacity alongside the Mobility docket.
Renowned producer Clement “Clemo” Rapudo moves from City Culture, Arts and Tourism to head Smart Nairobi, replacing him with Zipporah Mwangi.
The executive shake-up came hours after the county announced the creation of six new administrative units—referred to as Boroughs—aimed at enhancing service delivery across the capital. The new Boroughs include Western, Northern, Southern, Eastern, South Eastern and Central, each headed by a designated manager.
Janet Waeni Kimeu will lead the Western Borough, John Saruni will head Northern, Darasso Luka Wario will take Southern, George Muga will oversee Eastern, Susan Wanjiru Gichamba will run South Eastern, and Charles Baldy Mabonga will manage the Central Borough.
In an internal memo, Acting County Secretary Akumali stated that the redeployments across the Boroughs, Green Nairobi Sector, and Built Environment and Urban Planning Sector were carried out in line with Sections 48 and 72(2) of the County Government Act.
The latest changes signal an ongoing reorganization within City Hall as Sakaja seeks to streamline county operations and assert stronger control over a team often marked by tensions, turf wars, and public controversy.
