Impressions of Dr Carlos Guerra?

Hi,
I contacted Dr Carlos Guerra in Mexico (San Jorge hospital) and I wanted to know what folks here think about him/what experience as a patient of his do you have.
I had an appointment with Carlos and it seems that the vaginoplasty I want (acellular dermal matrix seeded with tissue - vagina canal) and external aesthetic is possible, so I want some patient feedback to know any issues/complications/warning signs or even recommendations that past patients have.
Thanks!
