John Peng does not have an adequate amount of comments to generate the sentiment analysis.
My interaction with John Peng was the worst experience I have ever had with a doctor. My normal Physician could not see me, so I was to see Peng instead. He changed my course of care that I have been on for 7 years without ever meeting me and prescribed me an entirely new medication. He was not my primary and I will likely never see him again and yet he took it solely upon himself to change what 4 other doctors have deemed my proper course of treatment.
