I had my surgery with Dr. Alberto Carlos 7 months ago, a gastric sleeve. I use to weight 92 kilos I have dropped 30 kilograms I am 5 kilogram shy from my goal. The doctor and all of his staff are vert caring. There wasn’t any complication whatsoever They were there for me before and after the surgery by phone, since I live in Culiacán. Highly recommended, thank you Dr. Carlos and Dr. Monica for chaning my life. The best decision I have made, God bless you all.
