Dr. Anez is a wonderful, caring compassionate surgeon. He did a great job with my open gastric bypass.

I also had my gallbladder removed 15 months later with him and you wouldn't even know I had two procedures with him because the markings are so faint. His office staff is great and very supportive.

You can't ask for a better bariatric support team and gifted surgeon in the Washington DC area!
