Patient Reviews, Ratings

“When my health care here in the US denied my revision surgery (I had a lap band in 2007 and never really worked well), I started researching private facilities that specialize in Bariatric Surgery. OCC reviews were fantastic but naturally was a little scared about going to Mexico. I had nothing to worry about. From start to finish to continued follow up two months post-op, Dr. Ortiz and the staff at OCC are top-notch and this will be the best decision I have made for my health. They make the process so easy from airport pick up and complete transportation, Hotel, etc. I ended up going alone and was in great hands both with the clinic and hotel and even a little sightseeing. I have already lost 25 pounds since March 5, 2020. The aftercare program keeps me on track and I feel totally supported. I can not recommend OCC enough!” – Review from RealSelf
