Nairobi County’s Chief Officer for Environment, Geoffrey Omatoke Mosiria, has spoken out after a throwback photo of him sandwiched between two women went viral online, sparking curiosity and chatter among Kenyans.
In a candid statement, Mosiria confirmed that the photo was taken during his campus years with his then-girlfriend (now wife) and her friend. “Yes, that’s me back in campus with my wife and her friend, when we were dating over 11 years ago. Today, by God’s grace, we are still walking this journey together, stronger than ever,” he clarified.
Turning the lighthearted moment into a lesson, Mosiria used the opportunity to encourage young people about relationships and marriage. “Marriage is not about rushing or appearances. It’s about choosing a partner who will stand with you through every season, until the race is fully run. Don’t just marry for the sake of it — marry your friend, your teammate, your life partner,” he advised. With a touch of humor, he added, “Back then I was still waiting for ndavu to come through 😅. Sherehe tulipiga tuka-graduate — now I’m a retired General na pombe zii.”
From Health Innovator to Environmental Reformer
Beyond the viral photo, Mosiria is no stranger to the public limelight. He currently serves as Chief Officer for Environment in Nairobi County, a role he assumed in August 2024 after Governor Johnson Sakaja reshuffled his cabinet.
Previously, he served as Chief Officer for Health Facilities, where he oversaw groundbreaking projects such as Nairobi’s first ICU at Mama Lucy Kibaki Hospital, new Renal Units, Blood Banks, CT scans (128-slice at Mama Lucy and 64-slice at Mbagathi), neonatal and newborn units, modern elevators, generators, and even a children’s playground at Mama Lucy Kibaki Hospital. His earlier career spanned nearly a decade as a hospital administrator at Pumwani Maternity, Mbagathi, and Mama Lucy hospitals.
In his current environmental docket, Mosiria has led bold initiatives to restore Nairobi’s cleanliness and green agenda. These include citywide cleanup operations, closure of illegal dumpsites, rollout of Nairobi’s first air quality monitoring network with 50 sensors, and pioneering a waste-to-energy project. He also spearheaded the draft Air Quality Action Plan 2025–2029 and Air Quality Regulations 2024, while promoting tree-planting campaigns in schools to instill environmental stewardship from a young age.
Community Leadership
Away from county work, Mosiria also serves as the Abagusii community spokesperson in Nairobi, a role bestowed on him in 2023. Governor Sakaja attended his installation, underscoring his influence beyond administrative duties.
More Than a Viral Photo
The viral throwback has, ironically, reinforced Mosiria’s reputation as not only a reformist county executive but also a relatable leader who grounds his public life in family values and personal discipline. From steering Nairobi’s health and environmental reforms to representing his community, Mosiria continues to demonstrate leadership that cuts across governance and personal life — reminding Kenyans that integrity in public service begins with authenticity at home.
