“Working with people who are overweight and obese gives me the opportunity to not only help provide a substantial improvement in their health, but also allows me to be part of the process by which our patients start a healthier, happier new life.”

Dr. Antonio Molina

“Having experienced obesity throughout most of my life and being a bariatric patient of Dr. López myself, I am able to feel more in touch with my patients, as this experience has allowed me to not only be a healthier human being, but a better, more understanding physician as well.”
