Lebogang Makoba
Botswana
I am a final-year Emergency Medicine resident at the University of Botswana, currently completing my training through a fellowship with the University of Cape Town. I graduated with a medical degree from the St. Petersburg State Pediatric Medical Academy in Russia, where I laid the foundation for a career deeply rooted in patient care, academic inquiry, and service. My core professional interests include point-of-care ultrasound, toxicology, and EMS and disaster management. I am passionate about advancing my expertise through postgraduate subspecialty training, particularly in ultrasound fellowship programs and emergency medical services.
Beyond clinical practice, I am actively involved in teaching and mentorship, currently training postgraduate paramedic students to help them succeed in their licensing examinations. I believe in nurturing the next generation of healthcare professionals through focused, accessible, and engaging education. Outside of medicine, I find purpose and joy in church outreach ministries and community service, which remain central to my values. I also love traveling and sharing knowledge with inquisitive minds—whether in a classroom, a clinical setting, or a casual conversation. Driven by curiosity and a desire to serve, I continually seek opportunities that combine clinical excellence, academic growth, and community impact.
