    Dr. Seng was very thorough and helpful. She reviewed my bloodwork in detail and answered my many questions with patience and expertise. I have great faith in her ability to help me as time progresses. I give her an outstanding rating! Very knowledgeable and "down to earth." Outstanding "bed side manner."

    I have always been somewhat happy with my treatment. Some of the side effects not so happy with. I am reaching the 5 year mark. I have remained this facility for others who have come down with breast cancer.

    My first appointment with Dr Seng was a positive. The office was clean, staff knowledgeable and efficient. My wait was under 15 minutes which is unheard of. I did have a little trouble locating the entrance but now I know. Thank you Southcoast Health for continuing to provide a positive healthcare experience.

    A few details were not explained- should I resume the medication I had been told to hold, had the Rx been sent to my pharmacy and a reminder to stay in the room for EKG tech. The nurse followed through to get the answers.

    I was able to be seen by another doctor when my provider was out sick. I really appreciated that since I needed to take time off work and didn't want to have to reschedule. Thank you

    Dr. Seng and her team are efficient, thorough and caring. The 'catch 22' is that they are amazing but, I was told yesterday I no longer need to return, as I'm 6 yrs. NED. Thanks for the amazing care during a trying time in my life.

    All the staff and providers are excellent. I went in for my appt feeling fine. I had lab work before my appt. When I went back into the waiting room I started to get hot and felt light headed. I went up to the PAR and quickly she got clinical staff to help. They brought me back into the exam room and gave me some water and had me lie down. The clinical staff and providers were so compassionate and they kept checking on me to make sure I was ok.

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.
