"Children with complicated gastrointestinal diseases, such as inflammatory bowel disease, chronic pancreatitis and liver obstruction, need specialized care. With few experts who focus on these conditions in children, families often struggle to find answers and treatment. Their unmet needs inspired me to become a gastroenterologist and work to improve care. Children with certain pancreas and liver conditions often require complex endoscopic procedures, but the doctors who perform those procedures treat mainly adults. Frustrated by how challenging it can be for families to obtain necessary treatments, I completed additional training to perform the procedures myself. This is an extremely rewarding part of my job because the procedures often lead to immediate improvement in a childs health. As one of only a handful of specialists in the country with my training and background, I strive to give families a clear plan and constant reassurance so they always know they have a knowledgeable partner at their side."

    • Holly Redmond, Wa 04.06.17

      Dr. Giefer supported our family through a year-long ordeal with Chronic Recurrent Pancreatitis in our 3 year old daughter. He coordinated treatments from the pain team, nutrition services, and our naturopath. Our daughter is now 8 years old and pain free. We now get to see Dr. Giefer once a year for check ups for her remaining exocrine pancreatic insufficiency and would recommend him to anyone for his expertise and bedside manner. All the Children's Hospital GI doctors are great, but Dr. Giefer is the best!

    • Tami Silverdale Wa 12.08.16

      Dr Giefer is outstanding! He truly cares for his patients I was so impressed how he listens and considers what is best I wish all were as wonderful!

    • Heather Bellevue, WA 09.08.16

      Our young daughter was diagnosed with Celiac. It was such a surprise to all of us, as she did not have any of the "classic" symptoms. Dr. Giefer was there for us, walk us through what the diagnosis meant, and the changes to our family. He is patient, kind, truly listens to us, and always focuses on her to see "how things are going". Check ups are inviting so we can continue her success and love his warm and friendly manner.

    • Kathryn Bellingham 12.15.15

      Dr. Giefer treated us with warmth and kindness. He honored our role in the decision making process by laying out the different options for treatment. He spoke to my child, never over her, and listened carefully, asking follow-up questions. He has a lovely manner, and we are very glad we were able to get into him. Everyone in the office is responsive and pleasant.

    • Jennifer Seattle WA 10.26.15

      Our daughter had stopped growing, and blood work indicated Celiac as the culprit. We were very apprehensive about endoscopy, and Dr. Giefer was amazing as he talked us through it. He gave pros and cons of deciding to confirm the diagnosis through endoscopy. We felt supported rather than pressured while trying to make a decision about our daughter's health. The procedure itself was quick and once again, Dr. Giefer made us comfortable and walked us through the results. He has a very practical approach to living with Celiac, and we so appreciate him and his staff as we begin our journey.

    • Maritza Seattle, WA 09.15.13

      My young daughter saw Dr. Giefer for persistent, stomach aches that she had been having for over a year. Dr. Giefer was both professional and kind with us and spoke gently and calmly to my little one. He put us all at ease. He was very thorough and when we decided as a team to do an endoscopy, Dr. Giefer showed the same kindness and calmness throughout the process. He gave us the results right away so that we did not have to wait days to know what the test showed. I would highly recommend Dr. Giefer!
