Accepting New Patients


Margaret Johnson Bia, MD, has specialized in kidney diseases, with an emphasis on transplant, for more than 30 years. She treats kidney patients after transplant and kidney donors at the Yale New Haven Transplantation Center.

A professor of medicine (nephrology) at Yale School of Medicine and former director of transplant medicine, Dr. Bia says she was inspired to work in kidney transplant when she saw what the field offered. “I was seduced by the pleasure of caring for recipients of kidney transplants who are given this second chance in life to come off dialysis and have a more complete life,” she says.

Dr. Bia says her patients carry incredible burdens of disease. “The longer I practice, the more awe I feel for my patients, and how they live with their burden with acceptance and dignity,” she says. She reassures patients by telling them, “I may not be able to cure your problem, but I can share with you what I know about what we can do to improve it, and what you can do to optimize your health.”
