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. These comments are the views and opinions of patients and are not endorsed by or necessarily reflect the views of Providence.

He listens attentively and he addresses the symptoms discussed. He is very caring and compassionate. Spent the time I needed to discuss my issues.

I am so completely satisfied.

Dr. Rgga actually listened [...]!

Dr. Rega and his staff are the best. I'm lucky to have them ...

It was a good overall experience for being my first visit to this office and my first time meeting Dr. Rega and staff.

I don't feel Dr. Rega really listened to me.

I was hoping to get some specific recommendations but instead I was mostly told, "it is up to you. You are the boss.

I did not feel like they really cared at all

a caring and thorough visit with anm.d. subbing for my appointed primary care doctor who was on vacation.

Seems to be somewhere else sometimes when I talk to him regarding my questions. Urgent care or just general care. My records are always up on the computer but I need to remind him of that.

Dr. Rega has been my provider for many years. He has always been very patient, understanding and listened intently to all my questions without interrupting. His concerns handling my medical problems have always been professional, knowledgeable and "top notch".

This was my first time meeting this provider. I requested a referral to a cardiac specialist (Dr. [...]) as he had been my follow up doctor after a heart attack 3 years ago and I have been experiencing chest pain at rest. These records are available in my file and Dr. Rega accessed them while speaking to me. Even after explaining that I had a complete blood workup following a physical at [...] in November with no anomalies, this provider requested another blood workup which, of course, showed the same results as the one in the November. He then requested an Echo cardiogram, a sleep study (claiming daytime fatigue that I did not mention) and a referral to Dr. [...]

the best of any of my visits

Always good both Dr. Rega and his staff.

This was my first time seeing this doctor. He was great. The only issue was that I had to wait about 20 minutes until the nurse got me. I was the only person in the waiting room for part of that.I am still going to go to the same doctor though. He's so much better than the family doctor I had been going to.

Office wait times could be better i.e., 15 min. or less.

the doctor also had back problems himself so, he knew exactly what I was goiing through and how to treat it. I saw him because of a cancellation. I was blessed to get him the same day I called with excruciating lower back pain. he was very verbal about what and why he was doing procedures to ascertain more precisely the exact cause of my lower back pain. I truly was blessed, of all the excellent doctors with Providence, I got the doctor who knew from personal experience how to diagnose and treat back pain. he also sent home with me a sheet of paper showing back exercises to do to strengthen my back; noting how many repetitions to do etc.... excellent care..... thank you.....

Provider took a phone call during appointment and left the room for several minutes leaving me in the room to wait further. When I left my appointment, I felt that I had just wasted an hour.


He was totally wrong about where to make a mental health referral. His referral was to an inpatient psychiatric but it was supposed to be outpatient, ie, a psychotherapist. No correction was made, no followup call with new/correct referral info. Apparently, it's up to me to find such a person while in a psychologically compromised state.

DR. Rega can only be rated good--he listens,and hears what you say--he sees you as a person,not just the next patient--he is right up to date on everything.therefore you can ask anything at all,and he takes every question seriously---

I've never been happy with this provider. Don't feel he cares. He seems to always counter anything you problem you bring. I will be looking for new provider.

I was given an extensive lecture against the treatment I am receiving from a chiropractor. That nterference with the Doctor Patient relationship was very unsettling.

I came to your office for a follow up from an ER visit where I had gone for upper right abdominal pain. I was told that all of the medicines that a previous doctor had prescribed were unnecessary, all of my previous diagnosis were dismissed, and it was implied that ALL of my pain and medical issues were due to depression. I am not depressed, and resent the dismissive nature that I was told that this [...] believed I am. His judgement of my so called "hard life". I don't have a hard life, I've worked hard and raised a family, I've NEVER used drugs, and I rarely drink a glass of why does he think he has a right to judge me and tell me what kind of life I've had because he's seen me for all of about 10 minutes. He tells me to stop taking a "non-narcotic" pain medication, he tells me that I need to see a mental health professional, and very lightly touches on the fact that I should follow up with the gastro doctors. So I was insulted, dismissed, and treated like a nut job until I had had enough of his belittling me and my intelligence and the intelligence of some wonderful caring doctors, and I left, angry. I've since received a letter from him stating that he again wanted to reiterate my need to stop taking pain medications that treat my fibromyalgia and arthritis, and go see a mental health doctor since this is all in my head and I'm depressed!

i called the office because i needed a refill for my [...]--they agreed to give me an extension on it,but dr. rega would not fill prescription again without seeing me---very commendable--i admire that he is so through ----

Always treated me with dignity and respect. Actually treated me like they liked me!!

He spent time to go over my questions and answered them for me.

Doctor was too over booked - is he the only doctor for this clinic? If so he needs help - he is a great doctor but on that day he was over booked and as a result did poorly. He is usually better - he needs help - clerks were great.

I always receive great care at this office.

Some uncertainties about the best solutions for some medical issues. Ex.- I indicated a tremor problem in my hands; no definite advice or referral was given, it was sort of left open-ended.
