I believe in taking a very proactive approach to the management of cardiac disorders. I am dedicated to providing the highest quality of care to my patients and will endeavor to insure that they receive the most up-to-date and advanced treatments for their cardiac issues. I work hard to educate my patients about their cardiac disorders so that they can actively participate in the management of their problems.

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.

Terrific experience.
Swedish Patient

One CANNOT beat the care or courtesy this provider or office personnel provides.
Swedish Patient

From the very beginning Dr. Casterella took us under his wing.
Swedish Patient

This provider is excellent
Swedish Patient

I have already recommended the doctor/clinic to friends. Dr. Casterella was kind, engaged, up to date on my history, compassionate. His nurse was as well.
Swedish Patient

Dr. Casterella was undoubtedly one of the best, most knowledgeable and most respectful (i.e. he listened to my concerns) providers I have seen.
Swedish Patient

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.
