  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 30 surveys. This ensures that the rating is accurate and statistically reliable.

I can not express what a great doctor I think Dr. Cook is. He always has the time to talk about any issues I have brought up. I am very thankful I have him for my doctor and feel I will live longer because of it. His level of professionalism is exemplary. He is a great doctor.

I was unable to see my regular doctor so saw another doctor; while he was very nice, he was somewhat dismissive of my concerns about what he was prescribing and did not give me sufficient information. When I found it on my own I insisted on stopping the antibiotic he prescribed. Further, he switched me from one antibiotic (that was not the right one) to one I did not want and did not communicate this to me so I spent too much time taking an ineffective antibiotic anyway. While I appreciated getting in to see someone right away, I don't think the treatment process was handled well or clearly.
