I strive to give our patients the best care by coordinating services among specialties and working as part of a multidisciplinary team.  Our families should rest assured that they are cared for by some of the best nurses, nephrologists, advanced practice providers and ancillary staff in the country.  My areas of interest and research include pediatric apheresis, peritoneal dialysis, and emergency preparedness for dialysis staff through hands-on simulation experiences.
