Dr. Metzger is terrific! I started working with him about 6 years ago after a recurrence with breast cancer. I was experiencing chronic fatigue. He truly cares about his patients! He listens carefully, does extensive research, and has excellent follow through. Believing that digestion is at the core of most health problems, if you can help the digestive process you can heal yourself! I am living proof! I would highly recommend Dr. Metzger!
