    Dr. Alachkar is wonderful. As a transplant patient I go once a year for an annual visit and the nephrologists at the transplant center rotate. I last saw Dr. Alachkar in the hospital four years ago after my transplant. She was the attending nephrologist and she was excellent. I was thrilled to see her again on this visit.
