Patient Ratings and Comments
About Our Survey

The Patient Rating score is based on responses given during the Consumer Assessment of Healthcare Providers and Systems (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. However, language that may contain profanity, slander, libel or private health information is removed. Comments reflect the views and opinions of patients. Comments are not endorsed by, nor do they necessarily reflect the views of, Providence.

Very attentive to my questions.

my care provider is the best of the best. listens, knows what to do and when, looks ahead for my needs.. am grateful for his care and his help

Dr/ Laretta is , in my opinion, a very good doctor

Doctor Laretta was very helpful and provided the information I needed.

Dr Laretta is great. unfortunately staff, telephone operator, receptionists are a stern and not as compassionate to patients. They take a stance that they are doing you a favor whenever they communicate with you. They need to be taught how to have a more cheery disposition and demeanor when communicating and in the presence of patients.

My primary physician usually gets with me every 3 months to go over thing we need to do


Doctor was very good and explained things well, listened well. [...]
