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.

I am extremely pleased to have Cr. Cannon as my follow up cardiologist after having open heart surgery in Spokane Washington. He came highly recommended.

Frustrated with ability to schedule appt. as requested by doctor for 3 months in future. (Unable to sched. appt. for June.)


I am confident that I am good hands with this provider.

Dr. Cannan sped up time for referral to pulmonary. It started as a routine visit and ended up with more tests to diagnose the problems. Very good.

Providence heart clinic and Dr. Cannon are expert in this field of health care.

I WAs diagnosed with a heart condition. I would have appreciated more discussion of the prognosis for my condition .and also discussion of non medical treatments and things i could do as well as drugs used to relax heart. life style choices, help with weight loss, There seems to be a disconnect between what I am hearing from my GP Perhaps I need another appointment with this specialist and/or the gp and perhaps another GP. Iam somewhat confused right now
