I knew many people that had surgery with Dr. 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 weight, trust me I tried.

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...

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’m finally living life to the fullest for the first time ever and I couldn’t be happier!

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...

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 hadn’t realized how much energy I didn’t have until I had the 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...

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.

A New Me

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. ...

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!

Over 100lbs gone!

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.

The Sleeve Changed My Life!

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...

Seeing others progress.

I was pushing 400 LBS, but enough was enough.

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...

My friend told me all about what OCC has to offer. I did it, and it was amazing.

Back to life

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.

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!

Gaining Control of My Life

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...
