Cameron's patient journey before gastric bypass surgery in Tijuana, MX at OCC
Cameron's patient journey after


-185 lbs

I can never express enough how grateful I am for what OCC has done for me.

I was considered overweight and obese my entire life. At 35, after years of failed diets, therapy, and research, I realized that the only way for me to permanently loose weight was to have bariatric surgery. My doctors in the US wrote letters to my insurance, emphasizing the medical necessity of this surgery. But after a year of back and forth, my insurance turned me down. I thought all hope was lost until I heard about OCC from a friend. I’d never even heard of traveling to Mexico for surgery, but, after researching and talking to the OCC, I was all in. And I’m so glad I made this choice. The amount of guidance and care I received from OCC from the moment I called for information has been better than anything I’ve experienced in the US. The procedure was smooth—I felt safe and in good hands the entire time.

It’s highly reputable reputation and accreditations.

I was sick of being sick. I suffered from type 2 diabetes and fatty liver disease. I have two small children and was sick of being tired all the time and sitting on the sidelines. I decided I didn’t want to live this life anymore. That’s when I reached out to OCC and it was the best decision I ever made. I am now actually living and making each day count.

I needed a drastic change.

I had tried losing weight and failed on my own so many times before that I just knew I could no longer do it on my own. My health insurance benefits excluded weight loss surgery and I felt so defeated! I didn’t want the insurance companies to decide what I knew I needed. It wasn’t until I started searching for cash-pay costs that I ran across the OCC website (and several others). I looked at their testimonials and tried to find some of those people – I reached out to them on social media to get their thoughts. I started doing research on Dr. Ortiz. I researched the accreditations and certifications that the OCC held and was liking what I was learning. I looked into other facilities and Dr.’s, but none of them seemed to have as high of standards as OCC. After doing research and talking with others about their experiences both at OCC and at other facilities, I decided that it was time to get more information directly from OCC.

OCC, you gave me not only my life back, you gave me my smile back…

I have struggled with my weight my entire life. In the long run it became not only emotionally, but also medically necessary to make a drastic change in my life. I was recommended by a family friend who is also a Nurse Practitioner and she recommended me to OCC, specifically Dr. Ortiz. Of course I was apprehensive of the thought of having surgery in Mexico but she reassured me that she took care of several of OCC’s patients right here in my hometown and that if anyone knew exactly what they were doing it was OCC. I researched OCC as well as others, both domestic and foreign, and came to the conclusion that OCC was without a doubt one of the best, if not the best. From the first call to the coordinator to the moment I left Tijuana headed back home, I was treated with support, kindness, compassion, and empathy.

I did quite a bit of reading and felt OCC was the best choice and it was!

I have struggled with my weight for all of my adult years, my highest weight was 245 at one time. I maintained my weight loss around 165 lbs until about 2 years ago when my band started not holding any fluid and realized it had a leak. I started regaining weight and put on about 50 lbs. My experience with OCC and Dr. Ortiz was wonderful! I decided to revise to the gastric sleeve and everything was great, we stayed at a very nice hotel , and the staff there was just as good. I had excellent medical care from the start. I would absolutely recommend OCC to anyone who is struggling with their weight. I am now down about 80 lbs and have never felt better. I work out with a personal trainer and run 5ks!

Safety, professionalism, knowledge, accreditation.

I was tired of being fat, and for most 215 isn’t that bad. But for me I felt disgusting. I’m use to bring the pretty sexy one. Not the chubby funny girl. I didn’t know that out of country surgery was even a possibility. I had a friend have it done in Mexico and I was like I want that. I booked with another company and after research I found that they had a death and complications. They also used drain tubes which did not sound like fun! Then I found OCC and saw all the great reviews, no deaths and no drain tubes. I was so nervous yet excited. My experience was nothing but positive. I even came home early I was doing so well. I have tried every diet, I exercised regularly and I just kept gaining. This tool has helped me so much. I still continue to eat healthy and exercise regularly but now I actually see results or my hard work. This isn’t the easy way out you still have to put the work in.
