Former finance minister and current presidential advisor on economy and finance, Maria Kiwanuka, is mourning the loss of her youngest son, Nsereko Kyamukungubya Kiwanuka, widely known as “Kyamu.”
Nsereko, who once worked at dfcu Bank before moving to the United States, was found dead on Wednesday, September 3, 2025, in his rented apartment in Washington, DC.
According to the family, an initial postmortem showed that he suffered a heart attack.
They explained that Monday was a public holiday in the U.S., so Nsereko stayed home. On Tuesday he still had not gone to work, even though he had seemed healthy before. A family friend grew concerned and called the police.
When officers arrived, they found the apartment locked. They forced the door open and discovered him unresponsive, with the television still on and tuned to his favourite sports channel.
Before his passing, Nsereko had recently graduated with a Master’s in Business Administration from the University of Denver. He had also secured a job as a finance advisor at a U.S. real estate firm. His competence was so outstanding that his confirmation came within two months instead of the usual six. The family said he was excited about passing probation shortly before his death.
His uncle, Owek. Robert Wagwa Nsibirwa, the second deputy Katikkiro of Buganda, confirmed that arrangements are being made to repatriate his body and organise burial.
The loss comes less than a month after the passing of two other family members: Rhoda Nakibuuka Nsibirwa Kalema, a key family figure, and Nnaalongo Margret Kiwana, Maria Kiwanuka’s mother.
At dfcu Bank, Nsereko was recognised as a skilled professional in client relations. He worked as a pinnacle relations manager and managed a portfolio worth about $10 million.
Colleagues described him as dedicated, innovative, and highly competent. He introduced a client onboarding system that encouraged high-value transactions and launched campaigns promoting zero transaction costs.
These initiatives brought more than 150 cash-only traders into the banking system. Reports show that his efforts increased revenue by 35 percent and improved customer satisfaction by 50 percent.
Colleagues remembered him as self-driven, passionate, and committed to delivering exceptional value.
