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.

I am so glad that I have Dr. Tregillus as my doctor. I hope she stays here for a very long time so that I don't have to look for another doctor to care for me. Dr. Tregillus has been my doctor for ages and I am so grateful to have her as my personal doctor. She is the best as far as I am concerned.

[...] Dr. Leslie Tregillus is one of the best doctors I have ever had. She is kind, patient, caring, knowledgeable, compassionate, organized, thorough, gentle, soft-spoken but confident, and personable. Swedish is really lucky to have her as a provider. Last year I moved to Northeast Seattle but continue making the trek to West Seattle just so I can still get my primary care from Dr. Tregillus. She is fantastic.

Dr. Tregillus is the epitome of a caring and knowledgeable family practice physician. I've been a patient of hers since 2000 and have never had a complaint regarding her attention. She is very prompt in responding to my chart communications and office visits are always thorough and meet my expectations. I feel very fortunate to have her as my doctor.

Dr. Tregillus is wonderful, very competent, listens well, is concerned about my health. I and my wife recommend her very highly. Dr. Tregillus worked me-us into her office schedule in spite of a conflict with her personal schedule and she did so willingly.

I was expecting to see my normL Dr., Dr. [...] and was surprised when this Provider arrived. No one had told me that Dr. [...] was not available. This provider was good, but does toss out a lot of clinical names for illnesses and does not slow down to explain them. [...]

This provider misdiagnosed my issue as tendonitis. I have since seen another provider who diagnosed my issue as cat scratch disease and prescribed antibiotics. This is an infection that I had for over 12 days that was slowly getting worse. It is not acceptable that this provider diagnosed this incorrectly, it could have been a very dangerous situation. I will not be seeing this provider again.

I have been with Dr. Tregillus for years, as well as my family. She is very prompt with answering her e-mail, and when I can't get through on the phone, she has her assistant call me, or my wife to help in scheduling an appointment. When she is not available, a back up doctor answers.

Dr Tregillis brainstormed with me to come up with a plan for what is a very complex situation for me. She really valued my opinions and listened to what I had to say. She offered new possible treatments.

I can't imagine a better primary care provider than Leslie Tregillus. She spends the time needed, is very thorough, personable, up to date -- just a great person. Also very responsive on 'my chart' so I know if I have questions or concerns she will address them very soon after I ask.
