My journey to bariatrics sleeve surgery began in April 2016 as I started to research where to have the surgery done. I live in Arizona so I looked into what was available to me in Phoenix, then I looked into what Las Vegas had to offer and that's when I found Blossom Bariatrics. I started watching their UTube videos and liked what I was seeing. In May I had my first appointment that was very informative and very thorough. I have completed all my pre surgery test and appointments and I am now waiting for authorization from my insurance. This has so far been an amazing journey and the staff at Blossom have been fabulous! I highly recommend Blossom Bariatrics for your weight loss journey!!!
