Patient verified via Press Ganey

Dr. Marouf was extremely professional, friendly, and took the time to not only listen to me, but review the referral and ER visit information before he came into the exam room. He was very knowledgeable and explained his care plan clearly and made sure I understood everything. He asked a few times if I had any questions and made sure I knew if I had any more to call the office and ask. I left feeling that I was in very competent hands.
