Krista had her sleeve in October 2017. 

“After visiting with the staff at WLIA, I decided that the Sleeve was my best option for significant weight loss. I look back at the decision as the best tool I could have ever gotten to help me on my journey to a healthier me! I’m down almost 100 lbs, and I have so much more energy and longevity throughout the day! I just finished a half-marathon, and when I crossed the finish line I teared up thinking where I am now as opposed to where I had previously been. I am forever grateful to Dr. Orris and the staff for the newer, healthier, energetic me, thanks to the sleeve!”
