Who we are.


Who we are Mount Olive S Hospital

Mount Olive Sinai Hospital was founded by Dr. Moses Kioria and Mrs. Susan Wanderi on 12th January 1998 as Sinai Mount Hospital (Not to be confused with Sinai Hospital which came later, neither is it affiliated in anyway with Sinai Hospital). Mount Olive Sinai Hospital (Then known as Sinai Mount Hospital) was the first private hospital to open doors in Ongata Rongai town with the aim of providing affordable yet high quality medical and health care to the local and neighbouring community.

Our intention of offering comprehensive emergency, clinical and surgical services that exceeds our patients’ needs and expectations has been realized though we are always working hard to improve, we never allow compromise to the services that we offer. Our establishment now boasts a capacity of (32) thirty two beds.
