A heart for healing

MINNEOLA, Fla. — For Dr. John Nwosu, interventional cardiologist at AdventHealth Minneola, medicine is more than a profession. It is a calling shaped by faith, family and a lifelong commitment to caring for the whole person.

Originally from Nigeria, Dr. Nwosu grew up in a household where service to others was a way of life. His father was a pediatrician, and in a family where his siblings followed a path into medicine. From a young age, he witnessed what it meant to care for people with dignity, empathy and respect.

“My father taught us the importance of education and service to our community,” Dr. Nwosu recalls. “He showed me that medicine is not just about treating diseases. It’s about caring for people.”

That foundation guided Nwosu through some of the most rigorous medical training programs. After completing advanced training in Philadelphia, New Jersey and New York, he moved to Tennessee and later to Central Florida to be closer to loved ones.

When deciding where to practice, AdventHealth stood out for more than its clinical reputation. Its faith-based mission, inclusivity, and commitment to whole-person care aligned deeply with his own values.

“I was looking for a place that was sensitive to the needs of the community,” he says. “A place where faith, compassion and whole-person care aren’t just words, but lived every day.”

Just weeks into his role at AdventHealth Minneola, Dr. Nwosu says he already feels at home. Family remains at the center of his life. He treasures time spent together cooking, watching movies, playing soccer, travelling and gathering with loved ones.

“Family and faith are what makes me feel whole,” he says.

Those values take on added meaning during February, which recognizes both Black History Month and American Heart Month. In 2026, Black History Month marks its 100th anniversary, an important milestone that invites reflection on progress made and the work that remains ahead.

Nwosu’s perspective is shaped by his lived experience. For him, Black History Month is a time to pause, listen and deepen understanding of the resilience and challenges faced by Black communities, especially in health care.

“Health care is still tied to history,” Nwosu says. “There are gaps in research and treatment, challenges with access and issues of trust. Representation matters because it helps build that trust and provide opportunities.”

As one of fewer than 5% of cardiologists who are Black, he understands the significance of his presence. “It was an uphill task getting here and continues to be so staying here”. “It is satisfying when patients feel like I have their backs,” he says. “They feel seen. They feel like they have an advocate.”

His commitment to advocacy is deeply personal. During his residency, Nwosu’s mother faced serious heart disease and underwent open-heart surgery. At the time, she could barely walk to the car. Today, she plays with her grandchildren and enjoys a full, active life.

“That experience changed me,” he reflects. “I saw heart disease from both sides, as a physician and as a son. It reinforced why this work matters.”

In addition to patient care, Nwosu holds a master’s degree in health care management, driven by a desire to help shape systems that foster inclusiveness, improve outcomes while keeping compassion at the center. He is also passionate about mentoring the next generation of physicians.

“We have to create pathways,” he says. “We have to show young people that they belong here and then support them when they arrive.”
