Hello - I just got back yesterday from Monterrey. My doctor was Arturo Rodriguez. I was very impressed with Dr. R, his staff and the hospital. My mom and DH were a bit apprehensive about being in a "foreign" hospital but it was as modern and clean as the ones here.
I would do it again, plus the cost was so much less than here the Pacific NW. (I am self pay) You can have a bad experience anywhere if that is what you are expecting. I had a positive attitude and the expectation that all would go well, thus it did. In ten years or so when I need some "work" done on my face, I will most likely head back to Mexico.
