  • I was terrified and the staff was empathetic, kind, reassuring, calmed me down and were responsible for my ability to successfully complete my treatment.

  • A great experience in wellness. The team was professional and made my treatments easy to endure.

  • I thought the whole staff did an excellent job. They were there, they answered questions when I needed it and I can't say enough about that. I give you a five star.

  • My experience from beginning to end was outstanding. I felt comfortable having my health in the hands of Southcoast. The entire staff was amazing, especially [Name] and [Name].

  • Yes, from the first time I walked in to the last time I walked out it was excellent and it always made me feel comfortable and secure and... Everything was fine. It's like I didn't even have cancer. Thank you.

  • The staff there was excellent, caring and very respectable. Very friendly, made the patient feel very comfortable.

  • Going through cancer treatments especially during Covid, I was alone, but never felt alone. Forever grateful and blessed to have [Name],[Name] and [Name] by my side.

  • Everyone at the facility was absolutely excellent! Ask were great, knowledgeable, caring, treated you as they would want to be treated themselves. Absolutely awesome staff, from the front desk to the last person that you see when you have your treatment. Great just great!!

  • When I began my treatments back in May, the original greeter at the door was a bit sullen, but the greeter who eventually replaced her (I never did get her name) was a joy to see and chat with both entering and exitingthe Cancer Center. The security guards were also cheerful.

  • When I found out I had cancer I was really nervous. From the first appointment I knew I was in good hands. Everyone who came in contact with me was so professional. Southcoast was recommended by my best friend who had gone thru the same situation a few months before. Thankfully I took her advice. The Doctors and Staff were excellent. I can not thank them enough. While I hope I never need their services again I will always suggest and praise the Southcoast Cancer Center.

  • Serious condition to me, handle d well

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.
