Patient Comments (4)
in St Peters, MO |
Dr Diwakaran was very knowledgable and explained the findings from my tests and his evaluations to my level of satisfaction. He was very thorough and was not content to pass my symptoms off without some explanation. He ordered tests colonoscopy, endoscopy and eventually MRI until he was able to find out my condition (Pancreas divisum, congenital defect of pancreas). I would recommend him to anyone.
in St Charles, MO |
Dr DiWakaran is a very caring doctor. He has returned every phone call in a timely manner. He answers questions and is understanding of the patients concerns. I think very highly of him.
in Ballwin, MO |
Very approachable, took his time explaining and discussing my procedure.
in St Peters, MO |
Can not get through to him on phone or leave a message what kind of doctor can not afford an answering service?
