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.

Good experience, handle professional.
Swedish Patient

I went to Dr. Grassman due to his hand-on diagnosis and support to get an aortic valve replacement. I actually pre-emped my routine cardiologist Dr. [...] because of Dr/ Grassman's concern for my well being.

Swedish Patient

After waiting a very long time in the room, I was only with the provider for 5 minutes, if that. He asked me brief questions, said my test results were normal, then sent me on my way without even going over other reasons why I might be having the symptoms I was previously having.
Swedish Patient

Did not ackowledge introduction to my husband; no hand shake, etc.
Swedish Patient

Dr. Grassman has a very pleasant manner and does a good job of explaining what is going on.
