How likely are you to recommend Dr. Gruessner?
My spouse received a kidney pancreas transplant well Dr. Gruessner was in Tucson Arizona. It has now been 10 years since the surgery and he is doing well. Without the transplants he would’ve died. As he was on dialysis for one year. A big thank you to the doctor for his great compassion, care, concern and skills. Thank you, Beth Crowley.
