Good experience all the way around.

March 2, 2020 2:55 PM

It was a good experience. I do question the exam for very little was looked at. I complained of a tearing in my groin where I had Hernia Surgery 4 years ago. I can feel a thickness forming but the doctor did not notice it. He assured me that there was no concern, but the tearing feeling happens when I exercise, but I figure it might be from weak muscles.

March 2, 2020 2:55 PM

The assistances were very nice. I really appreciated the time Dr. Peterson took with me. He was late but I have no problem waiting for when it is my turn, I wanted him to take all the time we needed, and he did.

September 22, 2019 7:00 PM

We really like Dr Peterson. The reason for all the "no" answers is that we only see him every 6 months; not 3 months. We are very pleased with care and advice he gives.

Great experience as expected, especially in terms of wait time.

August 5, 2019 7:00 PM

when my former PCP retired, it was a big concern that I would find a new Doctor that would be a good match for me with all of my many health concerns and diseases. God blessed me with Dr Peterson. I feel confident that he is a perfect match for all of my healthcare needs.
