"Down to earth, Dr. Walker is a Dr. that you can feel at ease to talk to. Along with his staff, this is a Dr. You will know you're in Good hands! I didn't think there were other doctors out there that were like my primary doctor, (Dr. Lawson) who was the person who referred me to Dr. Walker. Especially when you have to go to specialists, it's usually not the experience of meeting someone who has the ambience to come across as not only a knowledgeable doctor but a great new friend who shows he cares."

"Dr George J Walker is an excellent Gastroenterologist MD. He cares about his patients and their whole health. He is easy to talk to and has helped me to get to my healthiest self. He has worked closely with my insurance company to help get the best medication for me. He has been my parents’ physician also. Dr Walker diagnosed my father’s Pancreatic Cancer in the very earliest stages. We were able to have three good years with our dad as he battled his cancer. We consider this a most precious gift and we give Dr Walker full credit for his thoroughness and his brilliant knowledge of the colon, pancreas and surrounding organs. I recommend Dr Walker to all my family and friends. His office staff is just as wonderful and helpful!"

"Dr. George Walker is an amazing doctor. He is extremely thorough and kind. You never feel rushed in his office. He try’s to answer all the questions you have and he asks tons of questions that even you haven’t thought of. He truly cares and wants you to feel better. I definitely recommend him to anyone who is in pain and needs to know why! His assistant Kristen is incredible! When dr. Walker was out of town, I sent her a message about my daughter and the pain she was in. She helped get all the tests ordered from another provider and set us up with an appt. We had all the tests done so when dr. Walker came back, he knew exactly where to start with her treatment. It is hard to find a team like that in the medical field these days!"

He took the time to return my phone call in person. He diagnosed a condition not related to his specialty that had not been identified by my primary care doctor. He took the time to call my primary care doctor to discuss his observations."

"I saw Dr. Walker because I’ve been experiencing more severe digestive issues lately. I’ve always had digestive issues so I’ve seen other GI doctors but no one has ever taken the time to really get to the root of my problem. I was so impressed by Dr. Walker and his entire staff when I saw him in the office for the first time. I finally found a doctor that really gets what I’m experiencing. Today I had an endoscopy and colonoscopy. I was so nervous but his team was amazing! The front desk, the prep nurse, anesthesiologists, procedure nurse and my release nurse we’re all so compassionate and professional. I wish I found them sooner. Looking forward to getting my results and feeling better. I highly recommend Dr. Walker and his team!"
