Clinical Associate Professor, Medicine - Nephrology

Sankar N. Niranjan, MD FASN

Dr. Niranjan is a nephrologist (specialist in kidney diseases) with specific interests in the care of cancer patients with kidney disease (Onconephrology), high blood pressure (Hypertension) and the prevention of kidney disease. 

A graduate of Kilpauk Medical College, India, he completed his medical residencies in the UK and at the University of Connecticut, where he served as Chief Medical Resident and a Nephrology Fellow. Since 2004, he served as an Attending Physician and Nephrologist at the St. Francis Hospital and Medical Center in Hartford, Connecticut, and was a partner at Greater Hartford Nephrology. He was also a Medical Director at DaVita Dialysis in Bloomfield, Connecticut until December 2023.

In addition to his clinical practice, he has mentored numerous young physicians and nephrology trainees as a community-based faculty member at the UCONN School of Medicine in Farmington, Connecticut. 

His passion for the prevention and early detection of kidney disease is evident in his active involvement in the National Kidney Foundation’s Kidney Early Evaluation Program (KEEP) in Connecticut. He has facilitated screenings at inner-city community events and minority places of worship, demonstrating his commitment to reaching diverse populations. Over the last five years, he has conducted kidney disease screening camps across Southern India (most recently in June 2024), screening over 500 patients in rural areas using the KEEP template. 

Dr. Niranjan is fluent in conversational Tamil, one of the oldest spoken languages in the world. He loves the outdoors and fitness - specifically hiking, bicycling and yoga. He has enjoyed traveling the world with his family. He is passionate about giving back to the community, and supports the education of underprivileged children in India through a US-based non-profit.
