Dr. Garrett R. Roll is a general surgeon who specializes in abdominal organ transplantation. He cares for both adults and children, performing liver and kidney transplants using living donors; complex procedures involving the liver, pancreas, gallbladder and bile ducts; and kidney autotransplants (removing a diseased kidney to treat a challenging problem with the ureter, then placing the kidney back into the patient). He also provides surgical care for patients with end-stage organ disease and patients on immunosuppressive therapies. His expertise includes using minimally invasive techniques.

Roll is an investigator on clinical trials looking at outcomes for organ transplant recipients and at advanced organ preservation (storing organs for future transplantation). He serves in leadership roles for several patient safety and quality improvement committees at UCSF, in addition to teaching medical students and residents. He is also on the editorial board of multiple peer-reviewed journals.

Roll earned his medical degree from the Lewis Katz School of Medicine at Temple University. He completed a residency in general surgery and a fellowship in abdominal transplant surgery at UCSF, while also studying liver cell therapy and liver regeneration in Dr. Holger Willenbring's laboratory. After completing his training, he was a senior international fellow in liver retrieval and transplant at Queen Elizabeth Hospital Birmingham, which has the busiest liver surgery unit in the United Kingdom. During this time, he gained experience with donation after circulatory death (DCD) liver transplantation and a method of preserving donated livers during transport called normothermic machine perfusion.

    I think this care provider did the what was required of him but he was a liver specialist and I have not had any problems since the transplant with my liver.
