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.

Peter Casterella and his staff are very professional, friendly, courteous. They are all excellent as a health care provider team.
Swedish Patient

Always good.
Swedish Patient

Bonus points because this doctor is familiar with the effects of Late Stage Lyme disease which has been very challenging to find.
Swedish Patient

Excellent job.
Swedish Patient

I have total confidence in Dr. Casterella and his staff
Swedish Patient

My care provider was excellent and he took the time to explain everything about my condition. I had questions and he answered each one clearly.
Swedish Patient

Dr. Casterella is the best physician I have had experience with. He is personable, knows his specialty and always makes me feel like I am his only patient. Dr. Casterella was instrumental in contacting another Swedish specialist because of concerns for non-heart related issues and he took the time to personally contact the physician about me special issues. Dr. Casterella scheduled me for an appointment the day after my procedure with the other physician to go over the results and clearly explain to how those issues relate to my heart issues. I leave each visit with Dr. Casterella feeling more confidnet about my heart issues and know that he is "on top of" whatever is going on with my condition. I seldom get this kind of attention from a physician.
Swedish Patient

Kind, patient, smart, empathetic, smart.
Swedish Patient

Dr. C. is world class in knowledge and an example any dr should aspire to in the sheer humanity he shows in relating to his patients. I have worked as support staff to specialists and been the patient to many specialists- both experiences have left me shaking my head at the arrogance and lack of bedside manner shown; Dr. C. is the exact opposite in the confidence he instills and the kindness he shows. he is the first dr who has made me cry in relief at his genuine care as opposed ti the sheer frustration and belittlement I've felt by providers.
Swedish Patient

Dr. Casterella is the epitome of what a physician should be... concern for the patient, listens well, explains things clearly, doesn't rush through the appointment time, makes the patient feel as though his problems are the only ones the physician is working on, and in my case helped me understand what was going on with my health.
