Sylvia started her work in India by buying a van and operating it as a mobile clinic. She opened her first hospital in 1985 and this was replaced by a new hospital in 2002.
Outpatient clinics are held daily and over 80,000 patients attend each year. Sylvia also provides a 24 hour medical service 7 days a week.
Particular areas of interest include preventative medicine, ante natal, cardiology, diabetes, kidney problems, rheumatology, physiotherapy and paediatrics. The hospital is also the government supported centre for HIV/AIDS diagnosis, counselling and treatment covering a population of 1.3 million people. 1500 Government nurses and 100 doctors have been trained by Sylvia's staff in this field. The centre has been awarded a Grade A rating by the Tamil Nadu government.
The hospital has 220 beds on a 12 acre site and has extensive facilities. These include 2 operating theatres, 19 dialysis machines, a CT scanner, X Ray and endoscopy machines, together with a pharmacy and a blood storage unit.

Total staffing is over 280 including 10 doctors and 120 nursing staff. A number of consultants visit at least one day per week to hold clinics in their speciality. Sylvia insists that all patients are treated with love and respect and while most pay a little towards their treatment, the poorest are treated free.
