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.

the nurse that I had called about my issue didn't listen enough but insisted that she knows what the doctor can and cannot do. It seems she has the last say. Very rude [...]

Iris Tamashiro was awesome. She's very information and took her time explaining thing to me.

While I did have an overall positive experience with my provider, I felt like the rest of my experience at the office was very poor. I was rushed through the office throughout the experience. I felt the provider was being rushed from one appointment to another without the time or ability to truly have a complete appointment with the flexibility to talk about any questions or concerns I may have had. I was rushed through the check-in process without the ability or time to finish my paperwork (even though I arrived very early to my appointment), and no one seemed to notice or care that the paperwork was left unfinished. [...] The overall experience felt like a rushed clinic with little attention payed to each individual patient, as opposed to just a number being shuffled through as quickly as possible. More significantly, it felt like this type of office would make it very easy for mistakes to be made, go unnoticed and potentially lead to negative outcomes. While my general experience with the provider herself was not bad, the rest of the experience was very poor, and would therefore greatly influence my recommendation to someone else about this office.

Dr. I stayed after her last patient to see me. Her nurse practitioner also stayed late to see me in follow-up. thank you ladies for the kindness and sensitivity,

I had to wait an hour - most of it in a packed and very loud waiting room. I found the whole situation to be very stressful and am not at all happy that my providers are not part of this very large group.

love the office!

Very courteous but need to work to reduce waiting time.

I am very pleased with how my first appointment went with with Dr. Iris. She was very courteous, quickly made me feel at ease, and answered all the questions and concerns I had.

I like the doctors and staff the office I visit. the office wasn't so clean when I visited last time. A nurse told me that she called me too many times in the waiting room and I was there entire time (I arrived before my appointment time and was called after 20mins of my appointment time). The nurses rolled her eyes like I wasn't listening. It wasn't a present feeling

I had an extremely unpleasant experience at the Providence OB/GYN office on [...] I arrived at 10:15 for my scheduled 10:30 appointment with Iris Tamashiro, NP. I waited a little over 30 minutes in the front waiting room, then was taken to the back waiting room. While waiting they tried to draw my blood- 3 pokes, no blood. Back to the waiting room. I was finally put in an exam room at 12:00, an hour and a half after my scheduled appointment time. The NP got to the room at 12:15, and was unable to get the vaginal ultrasound probe to work. She even had someone else come in to try to get the machine to work. She did a quick abdominal ultrasound to try to see if there was anything in my uterus, and couldn't see much (needed the transvaginal). At that point I left at 12:25. 135 minutes after arriving. I had to be home to relieve the person caring for my child. So after 2 hours and 10 minutes I left with nothing. Nothing. No idea if my miscarriage was complete or incomplete. I am a reasonable person, with reasonable expectations. And I get that delays happen. But I feel this was unacceptable. [...]

Iris was wonderful. I have no problem with her care. However, I called a day or two before my appointment to warn her about some issues regarding my body that I'd like her to be aware of. There was no voice mail. The office receptionist WAS AGGRESSIVE HOSTILE. I'm telling her some personal issues and it seemed like I was bothering her. I was extremely vexed when I got off the phone with her. Needless to say, Iris did get the message and they were prepared for me. I wanted to be handled with kid gloves and really wasn't over the phone. During the visit, I WAS handled gently and with grace & humor. It is a lovely office. I just got a receptionist on a bad day, I think. [...] Bummer.

Dr. Ishimaru is a phenomenal provider who always listened to my needs. She consistently put my mind at ease and made me feel confident going into the birth of my first child.

the nurse technician was very unprofessional. I made an appointment to confirm pregnancy, but bc I had taken three tests at home that showed positive she did not think medical confirmation was necessary.

I had a biopsy done during the visit in addition to the routine Pap test. I received the Pap results via My chart and sent Iris a message asking about the biopsy results (if they were separate & still pending). I got a reply via My Chart from the office stating she wasn't in that day to reply but then received a reply from her saying that yes she's still awaiting my biopsy results. then just a bit later I received those results via My Chart with a note from her helping to interpret the results as negative and no need to worry. and she will see me next year. I was so relieved to hear back so promptly.

Nothing. Exceptional clinician and human being.
