What Our Patients Are Saying
Weight Loss Surgery Patient Stories
I am only 3 months post op and have had a total weight loss of 98 pounds, I’ve dropped 4 shirt sizes, 4 pant sizes, necklaces fit better, I don’t need a seat belt extender when I travel, and that’s just the beginning. I am no longer invisible, I have confidence I have never had before, and now I have the opportunity to share my story and hopefully be an inspiration to others. This has been the hardest, most challenging, and terrifying experience of my life. However, I can also proudly say that this is the best decision I have ever made, and I am strong and I am fearless. I have about 70 more pounds until I reach my goal weight, and I’m confident that with the continued support of Dr. Stevenson and his team, and my amazing family and friends, I’ll achieve my goal and so many more.”
