  • Everything

  • i was actually able to see my provider before my appointment time by 10minutes.

  • You listen to the patíent's concerns and address them immediately. If not able to access the answer, I am addressed in a timely manner. Dr. Desnoyer's has an excellent bedside manner, demeanor, rapport, and is extremely well informed. I feel very comfortable with him as my primary physician.

  • Always very professional and courteous. Doctor always knowledgeable about my heart health.

  • After I checked in, the wait to have my weight and vital signs checked was very brief. The tech was very friendly and efficient. I was then taken to an exam room, and the wait to see Dr Desnoyers was also very brief. He asked questions and listened to my answers. He was very friendly and answered questions that I asked. He told me his plans on what he wanted to do to treat me and asked if I had any questions about his plans. Overall, the entire visit to the office was very pleasant. I would recommend Dr Desnoyers to anyone I know who might need a cardiologist.

  • Everything was well. This is the best care ever had and it was the fastest that I ever had.

  • That was very fast in calling me into the room and I got finished fast l wish all my appointments were this fast

  • Dr Desnoyers was great for me being a first time patient to cardiology and running lab work and finding a problem and responding very very promptly

  • Positive—This was the first time for me seeing this provider. Everyone was so nice and welcoming to me that I felt like I already belonged there. 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. That's when she told me I was supposed to go to the check out window to register.

  • The staff is always polite and knowledgeable.

  • that are great and i trust them with my health totally.

  • Good afternoon. I must say that Dr. Desnoyers office functions flawlessly. I arrived at 10 minutes to my appointment was seen by somebody at 2 minutes to my appointment and at the time of my appointment 11 a.m. Dr. Desnoyers walked into the room. That has settled the case with doctors these days and I applaud his punctuality and the professionalism of the staff. I was very impressed and I see a lot of doctors, both in New York and here. Thank you, South Coast.

  • 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.

  • Everyone was very nice. The girls at the front desk were very friendly and the lovely girl who took my blood pressure etc and brought us in the examining room was very professional and kind. She was truly lovely. The Dr. listened to me carefully and explained my next step. The visit was very good all round, as I had experienced in the past when I accompanied my husband to his appointment after his hospitalizationm,to this same office.

  • The doctor always does a great job at listening and taking care of what's needed to ensure that my health needs are being taken care of. The doctor & nurses/ medical assistants are always nice and professional, however the people at the front desk could stand to be a little more friendlier, and smile more!

Why does Southcoast publish survey ratings online?

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.
