It’s not where you came from, it’s about how adamant and focused you are that’s really important. Thanks to my doctor and a very special friend who introduced me to my new life. I am forever grateful to Dr. Alejandro López.”

"Three (3) years ago I decided to make a change in my life.. It wasn’t just a physical transformation but it turned out to be more than that. Now I'm in my own skin. The insecurities I used to have, that used to prevent me from being the person I really was, all along are now gone. I've definitely bloomed!!  I sure have changed! I’m ME now and enjoying life to the fullest!!"
