I was sleeved with Dr. Alvarez on August 7, 2010 and let me tell you it was AWESOME!! He is such a GREAT Dr and caring man. I have never received such prompt care. I saw either him or the other assisting MD 3-4 times a day. He also has an assistant, Jessica that is there during the day for anything you or your family needs. I am a nurse and I can say that this care was way beyond what you would receive in the states. I can not say enough nice things about my whole experience and I have lost 40 lbs!!! Best of Luck to you and feel free to personal message me!
