Kidney disease
Chronic kidney disease and end stage kidney disease has many causes with predominant causes being diabetes and high blood pressure. Early detection of chronic kidney disease and managing risk factors, avoiding medications that can cause and worsen kidney failure can prevent progression to dialysis.
Our practice goal is to help identify factors that cause progressive and worsening kidney failure and work with you closely to help mitigate these risk factors.
A team approach with your primary care and other specialists is essential to have the most optimum care delivered to you.

Starting with empathy
We understand fear, anxiety, apprehension and uncertainty faced with life changing diagnosis of kidney disease and kidney failure. We are here to listen to your concerns and work with you through these times.
While some forms of kidney disease are reversible, especially kidney disease related to dehydration or acute insult, many forms of kidney disease cause significant damage to the kidneys making one dialysis dependent (more about dialysis in another section)
Often patients come in to our office fearing the worst outcomes and we are here to review your condition and direct you with the most appropriate treatment plan. Sometimes treatment may be holding your hand for reassurance and repeat a test, and at other times much more. Either way, we are here for you.
