May 17, 2020 3:52 PM

I have no problem with Dr. Petersen except I did not like when hospitalists took over in hospital care. But since I have been doing that in hospitals I am use to it.

May 13, 2020 10:03 PM

Brent Peterson is a good doctor and is always helpful ,but I have nothing good to say about the office personnel. I have had many issues with them.

May 13, 2020 10:03 PM

There is a poor attitude in the office. when you speak to personnel it's clear they are just going thru the motions. I do not like dealing with them, I only like my doctor Brent Peterson.

May 13, 2020 4:46 PM

Always a good experience. I get what I go in for. I'd be careful with this question. A bad experience for a customer could be a bad outcome, but that should be expected when delivering bad news. But, it is an honest assessment of the situation.

Dr Petersen and the team out of the office on Ryan are very professional, caring and good at what they do.

Completely satisfied. This was my annual medication check up. Everything is working the way it should.

February 14, 2020 8:03 AM

Dr. Petersen is a good man who shows interest in you as something other than "another" patient. He asks about family, hobbies, where you go, or how you have fun. Always takes time to answer my list of questions.

February 13, 2020 11:07 AM

We reviewed my lab tests and physical examination results and their implications for my health goals. I am doing well and understand how to do even better.
