With over 40 years of medical experience spanning four countries, Dr. Obiajulu Ezenwabachili brings a depth of knowledge and clinical insight that is rare in today’s healthcare landscape.
Dr. Ezenwabachili began his medical training in Russia, graduating in 1984. He went on to practice extensively in Nigeria through 1990, where he gained invaluable hands-on experience treating a wide range of conditions in environments that demanded resourcefulness and sharp diagnostic instincts. He then relocated to the United Kingdom, where he completed training in Obstetrics and Gynaecology and practiced for four years in England before moving to the United States in 1995.
This international journey has shaped Dr. Ezenwabachili into a physician who relies not just on technology, but on listening, observation, and the kind of thorough clinical reasoning that comes from decades of real-world experience. While he fully embraces modern tools and diagnostics, his foundation is rooted in the art of medicine — knowing how to examine a patient carefully, ask the right questions, and connect the dots that others might miss.
A Doctor Who Stays With You
Dr. Ezenwabachili is a true primary care physician in every sense. He manages your health comprehensively, and his care doesn’t stop at the clinic door. If you need to be hospitalized, he will follow you at Memorial Hermann Southwest Hospital, located near his clinic, to personally oversee your care. When appropriate, he can arrange direct hospital admissions for his patients, bypassing the emergency department to get you the care you need faster.
He refers patients to specialists only when necessary, ensuring that you receive coordinated, continuous care with a physician who knows your full medical history.
