Dr. Marwan Assaleh MD, has been my primary doctor for many years. Dr. Assaleh is one of the most advanced doctors and scholars I have ever had. When no other doctor could locate the problem or give a solution, Dr. Assaleh would strategically find the root cause of the issue and give me the correct diagnosis and most innovative solution within minutes. Dr. Assaleh is a brilliant doctor and most authentic, on another level. What makes him so great, in addition to his level of expertise and experience, is his profound kindness and compassion. How much he truly cares about every one of his patients is extraordinary. I have personally seen people walk in to his office, needing help and feeling despair. After seeing the doctor, they would walk out with a big smile and with wonderful praises for the doctor. One elderly man once walked in and asked for Dr. Assaleh. He announced that everyone in the community says, that Dr. Assaleh is the best doctor around. He genuinely is. Furthermore, Dr. Assaleh has created an exceptionally warm environment at his office. He has an awesome team where everyone is so nice and helpful, and they all go out of their way to assist and accommodate the patients no matter how busy the office is at any particular time. A big shout out to Melinda, Chelsea, Morla, Amy, Destinee, Jael, Mavinelys, Laury, Keasha, Christina, and Isabella, for being so remarkably amazing. I would advise my family and friends to make Dr. Assaleh their primary doctor at the Optum location, 591 Summit Ave, Jersey City. I am deeply grateful and feel very blessed to have found Dr. Assaleh.
