"Going to Gastroenterology office can be very stressful. Not the case with Dr. Oussama Moussan, MD office. First person you have contact iss the receptionist- She was professional, personal, which made me Very relaxed. It did not stop there- the Nurse/Randi was exceptional in All areas. She is the Nurse you want by your side in emergency room situation. Last but not least, Dr. Moussan- What a Gem! Very kind, he knows how to operate his tools, and Very patient when answering my questions. I would recommend Dr. Moussan and his staff to do Gastroenterology!!"

"I absolutely love Dr. Moussan! He is very thorough and efficient. I have had Dr. Mousann for both a colonoscopy and upper endoscopy. He went over my health history before both procedures and continued to work to find a resolution to an ongoing condition. He has an excellent bedside manner and is very personable; which is hard to find given today's fast paced health care setting. "

"I tried to make an appointment but since I have a hearing handicap I could not understand the questions I was being asked. the connection was not good and he could not speak louder. I tried calling back but the same results. I decided to visit their office since i live nearby. the receptionist said that I could not make an appointment in person. it can only be made over the phone. I was shocked. I have 95% hearing loss and even with hearing aids I still do not hear very well. My secondary issue was that Moussan was booked out for 3 months !!! I cancelled my appointment. found another dr who booked me only 1 month out. Never going back to Moussan. he has too many patients and does not care about people with hearing handicaps. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
