He Left Johns Hopkins to Transform Africa’s Healthcare & Built a $243M Empire

Dr. Julius Oni, orthopedic surgeon, investor, and co-founder of Excite Capital, joins The Afropolitan Podcast to reveal how he left Johns Hopkins Hospital to transform Africa’s healthcare system—and why Nigeria is now one of the most powerful emerging markets for medical innovation, investment, and talent. From building a $243M real estate portfolio to returning home to tackle Nigeria’s $2B medical tourism gap, Julius opens up about the discipline, sacrifice, and purpose behind choosing legacy over comfort. He breaks down what it truly takes to move back, build systems in Africa, and deliver world-class care in a market where 220 million people are served by fewer than 500 orthopedic surgeons. He opens up about: ◼️ Why Nigeria’s $2B medical tourism crisis is Africa’s biggest opportunity ◼️ The business model behind building sustainable healthcare in emerging markets ◼️ Leaving a top U.S. hospital to pursue purpose — not prestige ◼️ How he built financial freedom through real estate before moving back ◼️ What African professionals must understand about risk, faith, and purpose ◼️ How Excite Capital grew to $243 million while empowering the diaspora If you’re a builder, investor, or African professional planning your “move back,” this episode will give you the frameworks, courage, and clarity to build boldly.
