Holley Hospital provides specialist services in surgery, maternity and obstetrics, orthopaedics, ophthalmics and caring for an increasing number infected with TB and HIV/AIDS. A large outpatients department cares for the growing local population.
The hospital is also recognised by the Nigerian Government as a place of excellence in the treatment of leprosy; this department is run in partnership with Leprosy Mission International.
A School of Nursing has also been built nearby and should be functioning within the near future.
Alongside this, faithful witness is given to Jesus Christ through word and action. Pastoral care is provided by staff from the nearby UEC church to meet the spiritual needs of patients and staff.
