The Jaslok Hospital & Research Centre is one of the oldest super speciality tertiary care private trust hospitals in the country. In the late 60s, when the establishment of large private hospitals was not common, the institution was conceptualised & endowed to the city of Mumbai by Seth Lokoomal Chanrai.

Seth Lokoomal Chanrai came from a family of philanthropists who had businesses in many countries. The family had already supported many small & large projects. Seth Lokoomal entrusted Dr Shantilal Mehta with the task of establishing an ultra-modern centrally located medical centre where people of all races and creeds could receive the benefits of advanced health care.

Jaslok Hospital & Research Centre was built at Dr G Deshmukh Marg, Peddar Road, which is a main artery of South Mumbai, overlooking the Arabian Sea. The name Jaslok was derived from the names of Seth Lokoomal & his wife Smt. Jasotibai. The hospital was inaugurated on 6th July 1973 by the erstwhile Prime Minister Mrs Indira Gandhi.

Jaslok Hospital & Research Centre is now a private, full-fledged multi-specialty hospital with 350 beds, out of which 75 are ICU beds. The number of consultants has increased from the initial 50 to over 300 & 200 resident doctors. It is also one of the biggest research centers in India, conducting regular research and clinical trials in various fields, often in collaboration with other institutions in India & abroad. The hospital has also played an important role in serving the less fortunate sections of society, which was an important part of the vision of its founders. 20% of the beds are for IS (Indigent section) and WS (Weaker section) category of patient.
