About

Dr. Marcos Castaneda has impacted the bariatric surgery programs at each hospital he’s served. At the Secretariat of Health of the Government of Mexico City, he implemented and developed the first bariatric surgery program in a Mexico City government hospital and performed more than 600 bariatric procedures during the three years he practiced there. He also taught colleagues there, establishing the hospital’s first formal bariatric surgery course. At the ObesCenter Medical Comprehensive Obesity Clinic in Mexico, Dr. Castaneda continued this legacy as the facility’s managing director, performing more than 1,000 bariatric procedures and continuing to instruct his colleagues in surgical techniques.

Dr. Castaneda currently serves as the head of the general surgery service at the Regional Hospital Tlalnepantla ISSEMYM in the State of Mexico. He’s established the facility’s esophageal, hernia, and bariatric surgery programs, as well as the Minimally Invasive Surgery Advanced Program, where he trains fellow surgeons in minimally invasive surgical techniques.

We have passed the most rigorous accreditations and now display a List of Awards and Designations of Quality bestowed upon the Hospital and the Surgeons. In order for the Obesity Control Center to be awarded the various distinctions and designations by third party quality accreditation organizations, we had to go through rigorous year-long reviews that examined every aspect of our practice, including the staff, surgeons, and facilities. We are one of only a few international hospitals to be awarded these designations. We are fully accredited as a Center of Excellence in Bariatric and Metabolic Surgery and our Surgeons have been designated Surgeons of Excellence in Bariatric and Metabolic Surgery, and have also obtained the Golden Seal awarded by the Joint Commission International that signifies that we have met the highest standards in patient safety and quality available in healthcare.
