5 stars Paula B Featured review
Dr. Abousaif and his staff are nothing short of professional and caring, he has a wonderful bedside manner. I put off my first colonoscopy out of fear of finding a doctor that could make me feel comfortable enough to having the procedure. A relatively new prep made the process tolerable and his explanation of the findings were easy to understand and made me feel like the next time will be that much easier. I would highly recommend Dr. Abousaif to anyone looking for a very good gastro doctor.
Thank-you for your kind words, we value you as a patient.
