Independent healthcare quality assurance, improvement and governance consultancy — serving oil & gas operators, multilateral organisations, NGOs and government health bodies across Nigeria and Sub-Saharan Africa.
"Bringing NHS-grade quality improvement discipline and Shell-tested operational rigour to healthcare systems across Sub-Saharan Africa."
Vantage Health Advisory is led by Dr Obinna Ezeji (MB BS, MRCGP) — a GMC-registered physician with over 25 years of senior leadership at the intersection of international corporate healthcare and NHS clinical governance.
Dr Ezeji served as Head of Clinical Services Commissioning and QIA Lead for Shell Health Nigeria, and held statutory board-level accountability at NHS Southwark CCG — overseeing performance contracts for Guy's & St Thomas' and King's College Hospital.
This combination — Dr Ezeji's insider knowledge of Shell's systems and standards, alongside NHS quality methodology pedigree — is genuinely rare. It means Vantage understands the Nigerian operating environment and international best practice with equal depth.
GMC Registered — Active on National Performers List. MB BS, MRCGP.
Shell ICS 300 Certified — Senior Leader Emergency Response. Shell Leadership Programme graduate.
NHS Appraiser — NHS England South East London.
In 2017, Dr Ezeji founded and launched the DHC — a national multi-CEO collaborative which united external healthcare provider CEOs and Managing Directors across Shell Companies in Nigeria under standardised international safety KPIs and clinical outcome frameworks at its establishment.
The first initiative of its kind in the Nigerian oil & gas sector at the time — conceived, designed, built, and governed by Dr Ezeji from inception.
Independent audits, accreditation preparation and standards compliance — ISO 15189, JCI, COHSASA, Shell HSSE frameworks. Rigorous, evidence-based, and operationally practical.
Structured QI programmes using NHS-proven methodologies — PDSA cycles, Model for Improvement, lean. KPI framework design and performance dashboards that drive measurable change.
M&E framework design, data quality review, and programme performance reporting for donors, operators, and government clients. Designed to meet international reporting standards.
Policy review, incident investigation support, Significant Event Analysis framework deployment, and governance structure design — drawing directly on Shell and NHS experience.
QA and QI methodology workshops for clinical and management teams. Bespoke programmes designed around your organisation's systems, culture, and improvement priorities.
Fractional Chief Medical Advisory arrangements — providing ongoing, senior-level QA oversight for organisations that need independent expertise without a full-time appointment.
Client Sectors
Shell, TotalEnergies, Seplat, Eni, Equinor and their healthcare contractor ecosystems across Nigeria and the region.
WHO, World Bank, IFC, AfDB, USAID implementing partners and bilateral development agencies.
MSF, IRC, JHPIEGO, Marie Stopes and other international organisations with Nigeria and SSA health programmes.
Federal and State Ministries of Health, NHIA, and government health agencies seeking international-standard improvement frameworks.
Most consultants operating in this space bring either international standards knowledge or local context. Rarely both. Vantage Health Advisory is built on the combination — and that is genuinely difficult to replicate.
Direct experience of Shell Companies in Nigeria's systems, culture, HSSE standards and contractor ecosystem. No other independent consultant in this space has operated from within.
NHS improvement frameworks are globally respected. Board-level commissioning experience at Southwark CCG with oversight of elite London teaching hospitals.
Deep understanding of both Nigerian operational realities and international best practice — simultaneously. Expat consultants and UK-only advisors cannot replicate this.
Active GMC registration and MRCGP. A practising physician leading a quality advisory practice — not a management consultant describing clinical systems from the outside.
Managed multi-million-pound NHS commissioning budgets. Founded a national healthcare collaborative. Digital health transformation experience from both NHS and Shell environments.
Whether you have a specific project in mind, want to explore a retained advisory arrangement, or simply want to understand how Dr Ezeji and Vantage Health Advisory could support your organisation — we would welcome the conversation.
