I knew many people that had surgery with Dr. Ariel Ortiz®. They loved him and loved their results. I was a bit hesitant at first. Let me tell you – it was the best thing I have ever done!
I could never lose the weight. I tried every fad diet, every pill they came out with, and nothing worked. I was giving up on myself. I wouldn’t get out of bed or talk to anyone. I was depressed, and disgusted with myself. When I heard about this surgery, I was scared at first. I looked into... Read MoreView all Before & After Patient Stories
After spending 25+ years of fad dieting and losing and gaining the same weight, I came to the realization that I was spending the majority of my time sitting on the sidelines and letting life just pass me by.
I was saying “no” to so many things in life because of my extra weight, causing not only myself, but my husband and my children to miss out on opportunities to live life to the fullest and make amazing memories. I’m also genetically predisposed to a long list of health issues including diab... Read MoreView all Before & After Patient Stories
After surgery, I worked very hard and was able to get to my current weight by the time I got married. It felt amazing to be in a dress I bought off the rack, and feeling beautiful on my wedding day was 100% worth having surgery.
I struggled with my weight since I was in elementary school and it really escalated when I got to college, where I had access to fast food 24/7. I had previously dieted and exercised 5-6 times a week for a couple of hours to lose a significant amount of weight, but any time a bump in the road of ...

I chose OCC because of its Surgeon & Hospital Accreditations. The standards to which they follow are high and high for a reason. There wasn’t really even a choice of other places to choose from. OCC is rated the best and has the best real personal reviews.
I have struggled with weight for the last 15 years. Up, down, up, down – you all know how it goes. Hey, I’m happy – let’s eat. I’m sad – time to eat. Let’s celebrate – let’s eat. What should we do now – I don’t know, but let’s eat. ... Read MoreView all Before & After Patient Stories
I had a close friend that told me about OCC and seeing her success was very inspiring! So I started reading about OCC and made the decision that it was the right thing for me too!
My name is Kylie and thanks to OCC, I’ve successfully lost 112 lbs and kept it off. Before finding OCC and making the decision to have the vertical sleeve gastrectomy, I tried weight loss programs, doctor-led diets and supplements, trainers, and various fitness programs with minimal success...

I had many friends who chose the OCC and they all had such amazing results. I did lots of research and quickly learned that Dr. Ariel Ortiz was one of the best for surgery. I had absolutely no hesitation when booking. I knew I was making the right choice.
I wasn’t always a bigger girl, but I went through a terrible breakup when I was 20. It led to me becoming an emotional eater and consuming a lot of alcohol. I quickly packed on the weight. When I got to my heaviest, I went through another nasty break up, and I finally decided I needed to do... Read MoreView all Before & After Patient Stories
Seeing others progress.
In December 2013, I had decided enough was enough. I didn’t know it at the time, but looking back now, I feel as though I had hit rock bottom. And let me tell you – once you’re there, you will start coming to the realization that something needs to be done. It started a few year... Read MoreView all Before & After Patient Stories
My friend told me all about what OCC has to offer. I did it, and it was amazing.
All I can say is if you are considering changing your life, don’t think about it too much, and do it with the pros. The whole OCC team helped me a lot and the day I got the surgery, I was born for the second time. Read MoreView all Before & After Patient Stories
I was ready to take control of my life so I started researching bariatric surgeries online.
I confirmed that my health insurance did not cover bariatric surgeries, so I started to research affordable options, and saw that there were all kinds of options in Tijuana. I looked carefully at several different clinics that offered Gastric Sleeve surgery, read tons and tons of testimonials, and reviews of the doctors and clinics. I decided to go with the OCC because all of the stories I read were positive. I am so happy I went with the OCC! I’ve been moderately overweight my whole life, but when I was 30 years old, I got out of a serious relationship, and my weight really packed on. Even though it was my decision to end the relationship, my self-indulgence in eating, drinking, shopping, and spending, spending, spending went co... Read MoreView all Before & After Patient Stories
Our Bariatric Surgery Procedures
At OCC, we have enhanced the traditional Gastric Sleeve. Our approach resolves the issue of leaks in the surgical staple line with a proprietary technique called “Double Buttress-Over-Sewing” technique that creates a leak-proof seal. This specialized technique has fewer complications, is lower cost, and leads to faster weight loss and reduces the side effect of chronic acid reflux by 64%.Read more about Gastric Sleeves
Many people come to OCC for revision surgery to correct a failed bariatric surgery. Our world-renowned bariatric surgeons have developed groundbreaking revision surgeries for people who are not achieving the results they expected or are suffering unpleasant side effects. The original surgery may have been performed with an outdated technique, was not properly performed, or over time, the stomach pouch stretched, and the weight regained.Read more about revisional surgery
The mini-gastric bypass procedure, also known as “single anastomosis gastric bypass,” is a bariatric surgery option that consists of creating a smaller stomach pouch and attaching the terminal part of the small intestine to the new stomach. The body’s normal digestive process is altered, restricting food intake and the number of calories the system can absorb. As a result, food bypasses a large part of the stomach and most of the small intestine. This procedure may be ideal when you need to revise a failed sleeve or other failed bariatric procedure.Read more about Mini Bypass Surgery
The surgeons and physicians at OCC are among the leading authorities on the gastric bypass procedure, having performed this surgery over a significant number of years. It is often recommended for the morbidly obese and, with our exclusive Dual Long Limb (DLL) procedure, it is also curing diabetes in a qualified group of patients.Read more about Gastric Bypass Surgery
An OCC exclusive, the newest weight-loss procedure to be introduced is known as the Stomach Sparing Gastric Sleeve. It involves creating a sleeve within the stomach that helps patients feel satisfied by food much faster and consume smaller amounts of food.Read more about Gastric Plication
The “BariClip” has dramatically advanced bariatric surgery. Rather than removing or altering the digestive system, a simple, 20-minute surgery to place the BariClip device reduces the size of your stomach, so you feel full and satisfied with less food. The procedure is simple, reversible, far less invasive, and one of the most exciting breakthroughs for treating obesity.Read more about Bariclip
Lap Band Surgery
At OCC, Lap Band surgery does not alter stomach anatomy. The procedure involves placing the Lap Band around the upper section of the stomach to create a smaller pouch to achieve a feeling of fullness with much less food. Dr. Ortiz has improved the Lap Band procedure, developing an exclusive stitching procedure called the “Ortiz Anti-Slip Stitch Procedure” for long-term weight loss success.Read more about Lap Bands
Metabolic syndrome refers to the health conditions associated with obesity, such as Type 2 diabetes, high blood pressure, high cholesterol, heart failure, chronic kidney disease, sleep apnea, and others. At OCC, we treat people who are suffering from these conditions to regain improved health through safe, effective, long-term weight loss. The surgery is performed laparoscopically for a faster recovery and shorter incisions.Read more about metabolic surgery

I made the right decision.
With no hesitation, I would highly recommend OCC to anyone considering Bariatric Surgery. I just had surgery on March 30, 2022, and everything from scheduling to pre/post diet with their awesome dietitian, to the actual surgery and recovery was smooth. They take care of their patients; the NEW facility is very modern and extremely clean. I did my research thoroughly, and in the end, I kept coming back to OCC and Dr. Ortiz as my surgery choice and I made the right decision.
My research said Dr Ortiz and Dr. Martinez with OCC in Tijuana are the best.
I started doing my research on the best doctors for weight loss surgery at the beginning of 2021. I live in the US, but my research said Dr Ortiz and Dr. Martinez with OCC in Tijuana are the best. From the moment I contacted the clinic I was very well taken care of, and my questions were always replied to and answered quickly. I traveled alone and was never afraid. Would I recommend OCC? Absolutely 1000%! Would I do it all over again? Without a doubt I have zero regrets!
An amazing, hassle-free experience!
What an amazing, hassle-free experience! This surgery is life altering in a positive way. I was a 210 lb. diabetic on five medications with my numbers going through the roof. I met a lady who rescues dogs and she told me about OCC. I finally had surgery and the NEXT DAY I no longer needed the medications. I am almost 4 months out- have lost 44 pounds, I feel great and amazing, and am off all diabetes meds. I love Dr. Ortiz but every single person at OCC works together to make this a seamless process.
I’m telling everyone about my wonderful experience…
This surgery was the most incredible experience. I NEVER had any pain. I kept asking the doctors why I didn't have pain!!! The clinic was spotless, and the staff extremely helpful. I was a little apprehensive traveling for such major surgery by myself, but I was able to easily get up and down within a few hours post-surgery! And I was out shopping at the Tijuana Walmart two days post-surgery! I am telling everyone I know about my wonderful experience ‘over the border’!!
…the best doctor I have ever gone to.
My daughter and I went to Dr. Ortiz on Jul 4th. He was the best doctor I have ever gone to. He and his staff were the BEST!!!! I would recommend him to anyone. My daughter is my world, and I would not just have her have surgery with just anyone, so I did some checking around and found nothing but GREAT things about him. When we got there, he came over and spoke to me. He was singing to my daughter and just made us feel good. I relaxed and just went with it. He gave us his cellphone number and told us to call anytime we had a problem or just a question. He lives in San Diego and travels every day to Mexico to perform the surgery. He is just the BEST!!!!!
We were treated like guests at a spa.
I applaud Dr. Ortiz and his professional staff at OCC! I'm a registered nurse, and was thrilled to see an immaculate surgery center, universal precautions and sterile technique being used without fail. We were treated like guests at a spa, and the procedure itself went smoothly. I will have no reservations about referring my friends and family to OCC for the gastric plication. Looking forward to a smaller me and better health!! Blessings!
