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!
