I am a urologist who specializes in the medical and surgical management of kidney stones. My practice focuses on comprehensive kidney stone management. I perform a high volume of kidney stone surgeries, including cases with complex anatomy or large kidney stone burden. In addition, I perform evaluations to determine the cause of stones and then provide specific recommendations to prevent future stones. During our visit, I look forward to learning about you and obtaining a thorough history of your past experiences with kidney stones.
