A doctor from this district, for this district
Dr. Dante Ruskin’s career has an unusual shape for a specialist of his seniority: after training and clinical service in Tamil Nadu’s largest teaching institutions, he came back.
The M.B.B.S. is from Tirunelveli Medical College; the formative hospital years were at Madras Medical College, Chennai — one of the country’s oldest and busiest medical institutions, where volume teaches pattern recognition that textbooks cannot. He could have stayed.
Instead, twenty-four years of that experience has been spent where it is scarcer and matters more: in Marthandam, treating farm labourers, rubber tappers, traders, teachers and their parents — often three generations of the same family, which is how a doctor comes to know that a patient’s sugar always drifts after the temple festival, or that a particular grandmother will never admit to skipping her evening dose.
Two specialities, one doctor
Most diabetes patients in this region are cared for by two separate worlds. One doctor manages the routine — tablets, HbA1c, diet advice. A different, unfamiliar team takes over if things turn critical: a diabetic coma, a severe infection, a stroke, a heart attack. The handover happens at the worst possible moment, when history matters most and there is least time to explain it.
Dr. Ruskin trained to hold both. As Chief Diabetologist, he manages the long, slow, patient work of sugar control across years.
As Critical Care Specialist (intensivist), he leads PPK Hospital’s 24×7 ICU. For a patient this means the doctor adjusting your insulin in a quiet outpatient room in March is the same one directing your care in intensive care in November — with your medicines, your kidney function and your history already in mind.
That continuity is not a marketing line; it changes the speed and quality of decisions when minutes matter.

How he practises
Three habits define the consultation.
Unhurried first visits — history, medicines and reports reviewed properly, feet examined, questions invited, because diabetes decisions made in four minutes get unmade within a year.
Written plans in plain language — what each medicine does, your personal sugar target, food advice built around the rice, tapioca and fish that are actually on your table, and the date to return.
Honest limits — no cure claims, no miracle regimens, and a clear explanation of what treatment can and cannot achieve. Diabetes rewards steadiness over drama; the practice is built accordingly.
Beyond the hospital
The camp network exists because of a simple observation: specialist care that requires a bus journey gets postponed until it becomes an emergency.
Rather than wait for patients to travel, Dr. Ruskin travels — monthly consulting days across Kanyakumari district and into southern Kerala, with PPK Hospital standing behind every camp as the referral and admission base.
For families whose children work in Chennai or Bangalore, video second opinions close the other gap: a son can now sit in on his mother’s diabetes review from eight hundred kilometres away.
