About
Bio
I am a urologist with a specialty interest in advanced laparoscopic surgery, endourology, and the medical and surgical management of kidney stones. I spend about 20% of my time dedicated to research focusing on new minimally invasive imaging and treatment technologies for kidney stones. I also study the epidemiology of dietary and lifestyle factors as they relate to kidney stone formation. I have kidney stones myself, and so I understand the pain and discomfort that comes with passing a kidney stone and really focus on the prevention of future kidney stones. I love living in Seattle with my wonderful wife and two young sons.
