Sefako Makgatho Health Sciences University (SMU) continues to produce visionary healthcare leaders who make a global impact. Among its distinguished alumni is Dr Realeboga Sebitso, a dynamic medical professional whose career exemplifies excellence, resilience, and innovation. At just 31, he serves as the Lead Medical Officer at Carnival Corporation, a role that has taken him across more than 45 countries, refining his expertise in emergency and maritime medicine. As one of the few young black professionals in senior leadership, Sebitso is not only shaping strategic healthcare decisions but also championing inclusive leadership in a highly competitive industry. His remarkable journey is a testament to SMU’s commitment to nurturing world-class medical professionals who transform healthcare on a global scale.
Reflecting on his medical journey, Sebitso shares: “I have always been driven by a desire to make a meaningful impact. Medicine offered a path to help people at their most vulnerable moments.” His time at Sefako Makgatho Health Sciences University (SMU) played a pivotal role in shaping his career, providing not only academic knowledge but also leadership opportunities through mentorship programmes and student governance.
Balancing rigorous academic demands with leadership roles was challenging, but he embraced each obstacle as a learning opportunity. “I learned to prioritise, lean on my support system, and remind myself of my long-term vision. Challenges are stepping stones,” he explains. His tenure as a Radio Presenter at SMU FM 97.1 further honed his ability to communicate effectively—an essential skill in both emergency settings and cross-cultural interactions aboard a cruise ship.
Though he is not yet a specialist, Sebitso found his calling in emergency medicine. “I have always been drawn to fast-paced environments and making a tangible difference in critical moments,” he says. His transition to maritime medicine allowed him to combine healthcare with his love for global travel. His path has been shaped by mentors such as Dr Junior Manyoni, Dr Kylen Swartzberg, Dr Paul Sandler, and Dr Sashen Murugan, whose clinical acumen, leadership, and dedication inspired him to pursue advanced training, including a Diploma in Primary Emergency Care.
Sebitso credits his postgraduate education for enhancing his clinical proficiency. “The Diploma in Primary Emergency Care strengthened my ability to manage complex emergencies with confidence, even in resource-limited settings,” he explains. His training has prepared him for high-pressure environments, whether at sea, in an emergency department, or in remote locations.
As a Lead Medical Officer, Sebitso’s role extends beyond patient care. He is responsible for managing medical centre operations, emergency preparedness, team supervision, public health compliance, and crisis management. “One of the biggest responsibilities is ensuring the health and safety of thousands of passengers and crew members,” he notes. Despite the high demands, he finds joy in exploring different cultures, cuisines, and landmarks during his travels.
Practising medicine at sea presents unique challenges, from limited resources to remote emergencies. Sebitso emphasises adaptability and teamwork: “Every decision counts when you are miles away from the nearest hospital.” His approach to ensuring wellness onboard includes preventive care, infection control, and proactive public health measures.
One of the most challenging cases he handled was a passenger experiencing a life-threatening myocardial infarction. “Providing thrombolysis, coordinating an emergency evacuation in the middle of the ocean, and managing the patient under extreme pressure required calmness, teamwork, and clear communication,” he recalls. As a senior officer, he balances clinical responsibilities with administrative duties by staying organised and empowering his team.
With a diverse team and patients from different backgrounds, Sebitso values cultural competence. “I lead with respect, curiosity, and a willingness to learn from others,” he shares. Effective public health compliance requires diligence, attention to detail, and proactive communication with international health authorities.
Having worked across various healthcare systems, he has gained a broad perspective on global health. “With the right fundamental principles, medicine is practised similarly worldwide. This gives me confidence, even when responding to emergencies during flights,” he says with a chuckle.
Emergency medicine remains at the core of Sebitso’s passion. “It is dynamic, fast-paced, and gives me an immense sense of purpose. The ability to make critical, life-saving decisions in high-pressure situations is both challenging and deeply fulfilling,” he explains. However, his exposure to maritime medicine has sparked an interest in merging the two fields. His ultimate goal is to develop a synergy between emergency and maritime medicine, ensuring that high-quality emergency care is accessible even in the most remote and unconventional settings.
Sebitso credits SMU for instilling a strong sense of service and excellence in him. “SMU nurtured principles that continue to guide me in every aspect of my career,” he says. Despite his international career, he remains committed to contributing to South Africa’s healthcare system, whether through mentorship, healthcare reforms, or practising emergency medicine.
He aims to become a global leader in maritime and emergency medicine, developing innovative healthcare solutions for remote settings. He hopes to be remembered as a trailblazer who pushed boundaries and demonstrated that leadership, compassion, and innovation can coexist in medicine. “Possibility is my greatest motivation. There is always more to learn, more lives to touch,” he says. His journey exemplifies what it means to be an unconventional doctor—one who leads, heals, and inspires on a global scale.
