      "Dr Walker has Patience explains everything so you understand. I have had stomach issues since I had surgery in 2002 and Dr Walker is the only Dr I have seen that has helped in sny way. I had Dr Cho until he retired, he was excellent as well. I feel like I'm making progress with these two Dr's and all they have done to help me. I recommend Dr Walker Thank you"

      "Dr Zierer is has the best bedside, caring attitude of any Doctor I have seen. He believes in treating patients with honesty, listens and always open to your feelings/suggestions. I feel extremely lucky to have him as my doctor because I am not an easy patient with multiple health problems. I can't suggest him more."

      "Caring! He took the time to talk with me prior to my procedure. By talking with me prior to the procedure my anxiety was less. His bedside manner is comforting, he sat down to talk with me instead of standing."
