My husband and I both saw Dr. Perri a couple of weeks ago. We have prior experience with good dermatologists in the DFW area, and he compares very well with them. A biopsy he did on my husband came back as melanoma and he is scheduled with a MOHS surgeon in The Woodlands for surgery on that. We did not recognize the place he biopsied as anything other than a flat brown area on his cheek, and did not mention it to him. However he immediately did a biopsy when he was checking out his face. We are so thankful that he did that, because melanoma is not something to ignore! We will be using him in the future.
