I don't believe that he is thorough enough.

November 27, 2019 2:43 PM

The nurse was very impersonal and my appointment was at 1:00pm, I arrived at 12:49 and checked in. I was called into the office at 1:40pm, Dr. Knox came in at 1:56pm. No apology for the hour wait at all, plus I do not believe that he was as thorough as he should have been. Plus they had incorrect information on my medication list which I have no idea where the information came from.

November 16, 2019 11:00 PM

good experience

November 16, 2019 11:00 PM

Took good amount of time with me to discuss and answer all my questions, concerns, and how to treat my condition.

Dr. Knox has been my Primary Care Physician for years. I respect him and trust him with my care.

July 7, 2019 7:00 PM

He needs a new medical scribe. He takes down inaccurate notes and we spend half of the appointment with Dr Knox looking through the tests to check that what I tell him is correct and what the scribe wrote is incorrect. I am unable to talk about all the issues I want to bring up with the doctor because we waste so much time fact checking.

June 25, 2019 7:00 PM

My appt was for an annual physical, but provider did not review my health/family history, immunizations or preventive health screenings. I had to ask for a mammogram referral as he was getting ready to leave. He did not ask if I had any health concerns whatsoever.

I went out of his office Dr. Knox the same way I came in with no answers or help
