Patient Ratings and Comments
About Our Survey

The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey. Responses are measured on a 10-point scale, with 10 being the best score. These scores are then translated to a 5-point scale in order to display results in a 5-star rating. Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

This provider will be retiring shortly. It is with great sadness I see him go - I will most likely seek cardiology f/u @ your Cherry Hill location.
Swedish Patient

This physician is retiring & seems very anxious to retired!
Swedish Patient

Dr Petersen, always shows concern to my health and well being, I am sadden that he is in the process of retiring. I always look forward to seeing him, not only because he is a great physician, but he has become a friend.
Swedish Patient

Provider refused to consider how tests would make my condition worse. He was rude and not into talking/listening to me.
Swedish Patient

Care ALWAYS excellent!!
Swedish Patient

Very good!
Swedish Patient

I like *Dr. Petersen. He was very nice. Problem: Ballard is too far from where I live.
Swedish Patient

Called me on weekend to check on me!!!
Swedish Patient

Again, "very good" is not a high enough rating - all should be "excellent."
