I had my surgery through Blossom with Dr. Umbach. I am nearly three years post op and am still maintaining my goal weight. Even though I no longer live in Vegas I am so glad I chose to have my surgery while I did live there. Dr. Umbach and his staff are amazing! Thanks to these wonderful people I lost 141 lbs in less than a year and am still living the dream today. VSG works! Thank you blossom bariatrics!
