Nephrologists specialize in the treatment of kidney disease, a common complication of diseases like diabetes and untreated hypertension. Mild kidney disease may be treated with medication and lifestyle changes, but renal failure often requires dialysis. Nephrologists Dr. Randy White, Dr. Canon Bessel and Dr. Michael Portner serve as consultants to help primary care providers minimize the impact of kidney disease on their patients. They manage diagnosis, treatment regimen and dialysis oversight for treatment of end stage renal disease.
