    Though he doesn't have much to say, I have liked Dr Casta because I can tell he's quite Intelligent, is genuinely contemplating my medical wellness, and I think he would speak frankly if he had an insight to my health that would help me.

    I have a lot of health issues and medications. The doctor was very thorough reviewing my chart and asked relevant questions. He took my concerns seriously.

    Very little talking by Dr. He is only on computer. For a physical only contact with complex patient was listening to heart and lungs.

    Dr. Didn't have much of a personality. I tried to make conversation but no response. All business and didn't feel very comfortable. I will try another Dr. Next time.

    Dr. Casta is pretty quick getting things done. He is "by the book" and goes by numbers more than the individual. There isn't much of a personal connection.
