“When most people think about nephrology, they tend to think of it in terms of dialysis and kidney failure. The truth is, there is a lot we can do these days to slow the progression of kidney disease.

“Nephrologists also manage hypertension and the cardiovascular complications of kidney failure. We treat everything from glomerulonephritis to polycystic kidney disease, and we can also help those who are suffering from kidney stones.”

Reminder: To protect all of our patients, you must wear a mask to enter any of our locations.
Public health guidance for masking related to vaccination status has NOT changed in healthcare settings.

Vaccine Appointment Scheduling

Patients age 12 and older can schedule a vaccine appointment on the State’s website. Please note, any patient under 18 needs a parent or guardian’s consent which can be found here.
