ADIOS Dr. Arthur Hassan Ahimbisibwe! A Devoted Pillar Of Nyamitanga SS & Champion of Humanity

“To live in hearts we leave behind is not to die.” – Thomas Campbell

On the evening of May 17, 2025, Nyamitanga Secondary School and the wider Ugandan public health community lost a cherished alumnus and national servant, Dr. Arthur Ahimbisibwe. That evening, at around 19:55, a message appeared in the Nyamitanga SS Old Students WhatsApp group:

“Unconfirmed sad news coming soon after confirmation 😭😭😭😭😭😭😭😭😭”

Moments before his passing, he recorded an audio clip from Kiryandongo Hospital in which he described the aftermath of his motorbike accident during his return from the Central Riders Association’s MX Lira Chapter Ride, en route from Lira to Kampala. His calm tone, even in distress, offering what now feels like a gentle farewell to the community he loved.

A Final Message of Gratitude

Dr. Arthur’s very last text in the Nyamitanga SS group arrived at 10:23:29 on May 17:

“@⁨HAKIMU NSUBUGA⁩, thx so much.
Colleagues, kindly join me to thank @⁨HAKIMU NSUBUGA⁩ 🤝🤝🤝🤝”

This salute celebrated Hakimu Nsubuga’s fulfillment of a pledge of two school beds toward the ongoing fundraising drive Arthur himself had launched. It perfectly captures his style: encouraging, inclusive, and ever–focused on delivering for his alma mater.

A Professional Life of Service and Impact

Dr. Arthur Ahimbisibwe was a specialized medical doctor and a passionate public health advocate with a deep desire to see a transformed, healthy society focused on prevention. At the time of his passing, he served as Senior Program Officer for Adult HIV Care and Treatment at Uganda’s Ministry of Health under the AIDS Control Program, funded through the CDC-MOH Cooperative Agreement. He guided the national rollout of adult antiretroviral therapy, saving countless lives through policy, training, and on-the-ground mentorship.

He previously served at:

• USAID RHITES-EC Project (2017–2020) as a Program Officer in Jinja;
• Kamwenge District (2012–2016), as Senior Medical Officer and head of Rukunyu Health Sub-District, where he managed both clinical and financial operations and successfully led the upgrade of the health center to district hospital status;
• Bundibugyo Hospital (2011–2012) as Hospital Superintendent;
• Comboni Missionary Hospital-Bushenyi (2011) as a Medical Officer.

With over a decade of frontline experience, he was known for his deep integrity, administrative discipline, and unwavering service in some of Uganda’s most remote and underserved districts.

Nyamitanga, Ntare, and Beyond

Arthur’s academic path began at Nganwa Junior School, continued through Ntare School (1996–2000, UCE; S5 PCB/SM), and culminated at Nyamitanga Secondary School, where he completed his UACE in 2002.

To clarify a point about his identity: Arthur Ahimbisibwe came from a devout Muslim household. His father was a well-known and respected Muslim in their community, so much so that their living room doubled as a mosque, serving as a place of prayer for the local faithful (this is what I had heard from him while we shared a class at Nyamitanga SS). Though Arthur was given a Christian name by his mother and raised with exposure to both traditions, it was during his time at Nyamitanga Secondary School that he made a deliberate and personal commitment to fully embrace Islam.
Nyamitanga SS, the only Islamic school environment he ever attended, became the spiritual ground where he revived his Islamic name, Hassan, a name less known to the public because he never used it on academic documents, but one that those closest to him fondly recall. While at Nyamitanga, he served as Vice Chairman of the Muslim Students Association, already showing signs of the leadership, discipline, and conviction that would define his life.

I had the privilege of sharing a classroom with him in Senior Six Science, where he offered PCB/Sub-Maths. Hassan was not only intelligent but also intensely focused. He dedicated what must have been 80% of his time to Biology, and it was common to find him immersed in his textbooks at nearly any hour. He had set a goal, and he pursued it with quiet intensity.
Though Nyamitanga was a co-educational school, Hassan remained remarkably focused, almost suspiciously indifferent to the distractions of teenage social life. While many of his type were adjusting to the mixed environment, Hassan stayed rooted in his studies and his faith.

One particular evening during Mock Exams, we were deep in revision when we heard the shattering of windowpanes in the distance. It became clear that unrest was brewing. Lights were being blown out, and the atmosphere was tense. Hassan, ever vigilant and committed to order, urged us to go investigate. He couldn’t bear the thought of the chaos disrupting our exams.
Physically larger and naturally assertive, Hassan led what we jokingly called a covert nighttime operation. Under his leadership, we moved swiftly in the dark, confronting and detaining the instigators. We gathered them in front of the Administration Block, and shortly afterward, the police arrived to secure the campus.
The next day, the headmaster, Mr. Rugasa Hakim, expressed his deep appreciation for what we had done and rewarded the entire school with a special meal. While the group effort was applauded, we all knew who had truly led the charge, Hassan Arthur Ahimbisibwe.
That night was more than just a memory of school heroics. It was a glimpse of the man he would become. A protector. A leader. A servant of the people.

Hassan didn’t wait for adulthood to step into responsibility. He had been wearing that mantle since we were boys.

He went on to earn his MBChB (Bachelor of Medicine and Surgery) from Gulu University (2004–2010) and later a Master of Public Health (MPH) from Cavendish University Uganda (2013–2014).

A Leader in Every Circle

Dr. Arthur was not only a national figure in public health but also a key leader within Nyamitanga SS Old Students’ Association. He had this very year been elected as the Old Students’ Representative on the Board of Governors on 21st January 2025 and also served as Chairman of the Interim Executive Committee that was formed after the BOG Representative elections. He, with immediate effect orchestrated major initiatives that included visiting the school that was followed by the students’ bed Fundraising drive and student sponsorships that he personally followed up on always leading by example.

He coined the group’s slogan “Tusimbudde” that later after the visit to the school was upgraded to “Twasimbula dda” which became a rallying call for action, growth, and unity.

A Final Ride, A Lasting Legacy

Carrying the Torch Forward

Dr. Arthur’s final words and actions remind us that leadership is about gratitude, recognition, and collective action. As we mourn, let us honor him by completing the projects he championed and by thanking those who step up just as he did for Hakimu Nsubuga.

In his own words, he described himself as:

“Self-driven with a passion to serve humanity… with a broad picture of seeing a healthy transformed community that considers prevention as its first priority.”

To his wife, Zaina, children, and extended family: Thank you for sharing Dr. Arthur A. Hassan with us.
To all Old Students and current students of Nyamitanga SS: Let us ride forward together, carrying his vision in our hearts.

Rest in Power, Dr. Arthur Hassan Ahimbisibwe.
Your journey inspired us; your friendship enriched us; your legacy unites us.
