President Gary Singer

Please join us as we congratulate our founder, Dr. Gary Singer who began his term as President of the Renal Physicians Association in April 2025. The RPA is a national organization dedicated to advancing kidney care through advocacy for patients, private practices, and effective health policy. He proudly represents our community to healthcare decision-makers at every level.

What is Nephrology?

Nephrology is a subspecialty of internal medicine which centers around the treatment, diagnosis, and management of kidney function. This includes renal (kidney) replacement therapy like dialysis and kidney transplantation.

Nephrologists are experts in the care and function of your kidneys.

While urologists treat surgical and structural conditions of the urinary tract, nephrologists specialize in kidney function, disease prevention, and non-surgical management.

A nephrologist's education consists of medical school, a residency in internal medicine and an additional multi year fellowship in the specialty of nephrology.

They are equipped to treat such conditions affecting the kidneys as hypertension, autoimmune diseases, acute kidney injury and electrolyte issues.
