Dr. Montalvo has been outstanding. He is there no matter what you need. To guide you and support ❤️. My advice: follow the doctor's orders, and you will be fine.

Dr. Montalvo did my gastric sleeve in March and he did a great job! I have small, clean-cut incisions; I think they will be tiny scars. He came to see me before and after surgery in my hospital room. He answered all of my questions thoroughly (and without using medical jargon that I couldn't understand). On top of that, he was very kind and respectful.
