These charitable services were started in 1987 when Dr Kumar, along with two colleagues, set up the M.L. Dhawale Trust. Initially, the trio funded the trust which opened clinics in urban slums of Mumbai in areas like Jogeshwari, Malad and Masjid Bunder to serve mathadi workers (porters). Work also started in Palghar and soon the services were extended to rural areas, including adivasi pockets. Today, there are seven clinics in Mumbai and four in Pune. Some of these-in Palghar and in Mahul and Jogeshwari in Mumbai-are free while the rest are subsidised. The adivasis and the slum dwellers pay just Re 1 or Rs 2 for a week's treatment.
