Nephrology and kidney care
Northbay Health nephrologists care for your kidneys, from early disease through dialysis and transplant care
Comprehensive kidney care
Your kidneys quietly do some of the most important work in your body: filtering waste, balancing fluids and regulating blood pressure. When that work is disrupted, our team is here to help.
Led by Steven Ong, MD, our nephrology group provides hospital nephrology coverage every day of the year, plus outpatient kidney care in Fairfield.
Our nephrologists care for adults at every stage of kidney disease. We see patients referred for chronic kidney disease (CKD) or hypertension, hospitalized with a sudden kidney injury – or in need of ongoing dialysis or transplant support. Whatever brought you here, our team builds a plan around your kidneys, your labs and your goals.
The earlier we're involved, the more we can do to slow kidney disease and help you delay or potentially avoid dialysis. When dialysis does become necessary, we make sure you have every treatment option and a team behind you at every step.

Our expert nephrology team can help with a wide range of symptoms and situations, including:
