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 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.

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.

I have been seeing Dr. Tregillus for 18 years...that alone says a lot. She is friendly, professional, efficient, knowledgeable. She was truly caring when I first [...]; she was thorough in assessment and follow-up...as she is for other health issues I have. I can freely express my feelings and questions, and I receive excellent feedback. Dr. Tregillus makes me feel well cared for.
