Our Team: Transplant Nephrologists

The experienced transplant nephrologists at California Pacific Medical Center provide personal care with a focus on managing the entire transplant process to an excellent outcome. The program's long history of success is a reflection of their expertise. Our philosophy is that transplantation is not an isolated surgical procedure, but part of the continuum of medical care in the treatment of patients with end-stage renal disease.
