Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

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.

I see Dr. Mertz at the downtown office and would recommend him to all my family and friends. He achieved what other doctor's could not and that was find what was causing my head congestion and allergies. I have one negative complaint and that is the billing department. I had a billing question and tried calling at 3:15 pm. I was told the biller leaves at 3:00 pm, so if I had a question I should call before that which is unheard of and very inconvenient.
