How likely are you to recommend Dr. Mertz?
Out of the 10 Doctors I have seen at UPMC and AHN, Dr. Mertz was the only doctor to figure out that I had an IgG deficiency. He reviewed all of my records from when I was a child, during and after chemotherapy, did a number of test to figure out what I had. I’d recommend him to my friends and family. 10/10.
