37 y/o wanting a change

I've always been on the heavier side, or like most people like to say "thick". I always thought about plastic surgery but never really took it serious enough until now. I'm tired of carrying around the extra weight I'm not looking to be a size 2, I just want to have that sexy hour glass figure and feel good about my body. After reading some of the reviews and other people's experiences I...

Dr. Alejandro Lopez is the greatest doctor I’ve had the privilege of knowing. Best bedside manners you can hope for, kind and funny! He introduced himself almost as soon as I got to the hospital.

I was very uneasy at f...

Let me tell...

WLS a total success thanks to Dr. Lopez

Wish all my doctors were like Dr. Alejandro Lopez. He’s the best, made me feel very comfortable, encouraged me to ask questions about the procedure, follow up and lifestyle changes I’d have to make; he answered patiently and thoroughly. I was told my surgery went as planned and so far I haven’t had any complication. It’s been tough to balance my life and physical activity as well as diets b...

Absolutely wonderful experience; Dr. Alejandro Lopez is the Best Dr. ever! - Tijuana, MX

My experience traveling to Tijuana all the way from Vancouver for my Gastric Sleeve Surgery with Dr. Alejandro Lopez-Ortega was absolutely wonderful. At the time I was very nervous about the whole journey; starting with traveling abroad, not knowing how to speak Spanish, the surgery, etc. The quality of services provided and the level of professionalism from everyone on the staff, to the...

Finally Made the Decision to Do This ~ Gastric Sleeve - Tijuana, MX

As so many before me, I'm tired of the yo-yo'ing weight. A few years ago, I lost a little over 60lbs just by counting calories. A small injury that had nothing to do with eating sidetracked me and I gained all of it back plus some. I just went on about my business over the years not paying much attention to my weight or the scale. I knew what I needed to do to try and lose weight but had...
