I am experienced in treating all aspects of kidney disease, including chronic kidney problems, hypertension, kidney stones and electrolyte problems. I have a particular interest in the care of kidney transplant patients. I emphasize educating my patients about their disease and empowering them to participate fully in their treatment decisions. My outside interests include cycling, swimming and spending time with my husband and two children.
