The conceptualization of what is now known as GRASSROOT HEALTH AID PROMOTION ORGANISATION (GHAPO) was started in Houston, Texas by Dr. (Mrs.) Esther Imogu in 2005. She graduated from College of Medicine, University of Lagos in 1997 and relocated to United States in November 2000. While taking her United States Medical Board exams, which she passed and received her Educational Commission for Foreign Medical Graduates (ECFMG) Certification in 2001, she also became a licensed Registered Nurse in 2004. Later she obtained an Masters of Public Health degree from The University of Texas School of Public Health, Houston, Texas in 2006. She worked as a critical care provider in The Methodist Hospital, Medical Center, Houston, where she was also involved in research studies.
Her interest in the public health and its observed impact at the grassroot level and among the underprivileged started when she had to take a break from work and studies in 2005 and return to Nigeria for a visit. Her encounter with colleagues and the personal experiences she was exposed to was amplified by the increasing occurrence of patients testing positive to HIV and HBV and sudden death in patients, family members confirm were known hypertensives. The poor economic situation observed affected family units, leading in some cases to students lacking appropriate guidance to succeed were observed involved in unacceptable social vices. There were so much issues confronting people that needed intervention, thus came about the birth of GHAPO Nigeria in 2OO5.
