Constructive—Nobody told me to go to the check out window to schedule my blood work so I just took a seat until a lab technician came out and I asked her about it since I had been waiting for a while.

  • when ever i go to i am treated with care an i tell every one i always love to go there because they everyone is wonderful .

  • He make you feel like you're important

  • They did a great job from the start, from the intake to the nurse who came in first and then of course, Dr. Desnoyers was excellent as always. Answered all my questions and was extremely thorough. Thanks.

  • There was medical staff with me all the time that I was there. And letting me know what was going to happen next. And at the end of my visit the doctor would tell me the result. Neg. Or positive. Then the doctor would give me my next appointment. He would say any. New pains call us right away .

  • Dr. Desnoyers did a physical assessment, reviewed my medications, lab work, inquired about my physical activity, and ordered an EKG. The office visit was calm, relaxed and thorough beginning with the check-in and appointment coordinator and the medical assistant, [Name]

  • Dr. Desnoyer actually seems concerned with my health issues. I have other providers that seem less than enthusiastic regarding my health issues.

  • Did very well can't think of anything to improve my visit.

  • There was not an appointment for labs. It was scheduled after my appointment. It always used to be scheduled first. I don't understand why things have changed.

  • Didn't wait long to see doctor n when I did he always explains everything to Me he is a very good doctor I always recommend him to everyone I know

  • The staff greets you in a friendly & supportive manner. Dr. Desnoyers arrives with a grin, sits down with you, goes over all your test results, & discusses your health & expectations without hurrying you in any way.

  • Everyone in the office was nice and very helpful, I am very impressed that the office called me with my test results the next day.

  • Doctor was very professional.

  • Most of the time he, he, they do listen to what you're saying. Usually, their very good at it and they're very helpful. The only problem that I have is with some in doctor doctor's in the hospital, not so much with Dr. Desnoyers but with some of the other physicians that end up getting assigned to you. Because they don't listen to you and they don't communicate well with certain doctors and some of the communication that goes on from those Hospital doctors to Dr. Desnoyers sometimes I think that It's lack of communication where they should be, but more communication with the, with the cardiologist, versus what goes on with the doctor in the hospital. If you're still his lack of communication from hospital doctor's*


  • Got what I needed done in a timely manner

  • Everybody was very friendly, seemed well, informed and professional.

  • Dr Desnoyers has been my cardiologist for many years - he is so professional and yet personable - I trust him explicitly

  • Dr. Destroyer and his office staff are wonderful. Everyone treats you with such care and respect. They always treat you like you are their only patient.

  • Dr. Desnoyers is a caring individual who is always professional and I have all the faith in the world in he and his staff.

  • Dr Desnoyers listens to me and always has good advice. He takes better care of me than my PCP!

  • Everyone was kind and understanding Like this doctor he's a good doctor

  • The person who checked me in was rude . She called me over but didn't say window #3 or wave so I had no idea who was calling me and when I said that she said nothing to me, and just asked for my info and I said nothing has changed since I was here last week and she gave me a snappy remark like well I have to ask these questions and gave me an attitude because she didn't like that I had complained about not knowing what window to go to. Its very hard to hear at the check in and check out windows because of masks, the plexi glass shields, and because there are other people checking out and talking. Those are a couple areas that need improvement but the provider was great and so was the MA/or nurse that took my vitals.

  • He always greets me in a caring way especiallysince I am hard of hearing and he is very patient when talking with me.I have been hispatient for years and I would never think to change doctors.... Many of the doctors seem to have a time limit with their patients and rush them along....but not my doctor.

  • Keeps me alive

Southcoast Health physician profiles now feature star ratings.  Below, you’ll find frequently asked questions about our process for calculating the ratings.

Why does Southcoast publish survey ratings online?
Southcoast is dedicated to providing patients and consumers with helpful information about the quality of our patients’ experiences. Star ratings published on our physician biography pages are based on actual responses from patients of that particular physician to patient satisfaction surveys that are distributed and processed by a national patient satisfaction survey vendor.

Who receives the survey?
Our vendor sends surveys via SMS or email to all patients seen in our outpatient physician practices who have a valid smart phone number or email address on file with Southcoast Health. Surveys are sent to patients within a few days of their appointment.

How is the Patient Satisfaction Star Rating Calculated?
Star ratings are calculated using an average of all survey responses to each of three questions: Courtesy and Respect of Staff, Provider Overall Rating, and  Willingness to Recommend Provider’s Office.  The star rating displayed on our physicians’ main biography page represents the average of the three measures for that particular physician.
