John Oderah Agwunobi – The Consummate Admiral of Public Health


The 2004 Atlantic hurricane season was one of the worst and deadliest hurricane seasons of the 21st century. There were a total of nine hurricanes and 15 storms and tropical cyclones, half of which brushed or struck the United States and other Caribbean countries, causing about 3,270 deaths and about $61.2 billion damage in property, with the state of Florida being one of the most affected areas. However, on ground to help mitigate the effects of the devastation was a Nigerian-American paediatrician and health administrator, John Oderah Agwunobi.

Agwunobi coordinated and led the state public health emergency response efforts in saving lives and bringing relief to millions of people while serving as the secretary of health of the state of Florida under the administration of Governor Jeb Bush. Quite remarkably, prior to the hurricane of 2004, Agwunobi had led the response to the United States’ first-ever intentional anthrax attack in 2001. Thereafter, he guided the state of Florida’s efforts to prepare for, prevent, respond to and mitigate the effects of a bioterrorism attack.

In December 2005, Agwunobi was confirmed by the US Senate to be the Assistant Secretary of Health (ASH) of the US government and served as a member of the US Public Health Service Commissioned Corps, holding the rank of a 4-star Admiral.

As the ASH, Agwunobi oversaw the Office of the U.S. Surgeon General, Centres for Disease Control, National Institutes of Health, the FDA, HRSA, Indian Health Service, Office of Minority Health, as well as numerous other Public Health offices and programmes. He also served as the U.S. representative on the World Health Organisation executive board.

In 2007 Agwunobi was appointed as the senior vice president of Walmart stores Inc. and President of the retailer’s $30 billion Health and Wellness business, a position he occupied till 2014. At Walmart, Agwunobi was responsible for a chain of 4,000 retail, specialty and mail order pharmacies; more than 2,500 vision centers and 100 in-store convenient care clinics; and a pharmacy benefits management unit.

Background and education

Dr Agwunobi was born on 4 October, 1964 in Dundee, Agnus, Scotland, to a Nigerian father, Titus Chukwuma Agwunobi from Anambra State; and a Scottish mother – Veronica Marie Stuart Shaw.
