There is no publicly available rating for this care provider for one or more of the following reasons:
  1. He or she does not see patients in the outpatient clinic setting.
  2. He or she sees patients, but has not yet received the minimum number of Patient Satisfaction Reviews. To be eligible for display, we require a minimum of 40 surveys. This ensures that the rating is accurate and statistically reliable.
  3. He or she is a community provider, not a Geisinger-employed provider. Community providers tend to see patients in their own private outpatient practices, which we do not survey.

Provider expressed that he was "tired" which made me wonder if he was really listening to what I was saying. He also laughed at one of my concerns which made me again wonder if he was really concerned. I was having abdominal pain for several months and he did NOT listen to my bowel sounds or assess my abdomen other than a cursory palpation of the quadrants. He also wanted to start me on medication that "causes diarrhea for 2 weeks" 2 weeks prior to Christmas. How compliant do you think someone is going to be with that?

Dr. Duncan hurried too much, did not take time with me and my concerns. Increased my medicine which I didn't need. #1. He hurried too much.
