Best decision
From the minute I spoke to someone about wanting to learn about the procedure until now I have had nothing but the most caring, professional treatment. I have lost 37 pounds in 10 weeks, my goal is 55 pounds. I feel fantastic, the support is second to none. I feel great, no pain, no issues. This is a life altering procedure and I thank Bariendo for changing my life.

10 weeks
This was the best thing I could do for myself
I am two weeks post procedure and this is the best decision I've made for myself in a long, long, time. I looked at several clinics after choosing ESG and the aftercare at Bariendo was what sold me. Boy, have they lived up to the hype. From onboarding to my follow ups with my wellness councilor to the support from the Facebook community, this has been a great experience. If you're considering a bariatric procedure, do yourself a favor and talk to the people at Bariendo. They were not the least expensive company I spoke with, but the value of their support far exceeds and small differences in price.
