Dr. A was AMAZING! He was genuinely interested in hearing and learning about my issues. He was not rushed at all in our time together. And his knowledge of my respiratory problems instilled confidence in me, that there may be more that can be done to help my breathing issues.

Dr. Aboussouan was incredibly kind and was a great listener. He took all of my concerns seriously and was the first provider I saw who validated my concerns and symptoms. He is honest about the reality of your treatment decisions and will recommend what is best for you. Many doctors want to rush to a diagnosis, but he was more concerned with me as a human being than a patient to check off his list. I believe that more doctors should follow in his footsteps and prioritize a more humanist approach to treatment. Healthcare in America often feels like patients are just a number on a list to be seen and dismissed, but Dr. Aboussouan sees his patients as human beings, and I truly respect that.

I've had ALS for 11 years and dealt with so many doctors and specialists during that time, but Dr. A is by far one of the best I've ever interacted with. He is thorough and has an incredible bed side manner, always listening and patient. I can always reach him via MyChart, and he always responds quickly.

One of the most thoughtful Doctors at the Clinic.

Dr Aboussouan spoke knowledgeably, clearly, and with concern for my understanding of my health issues. The very best follow up I received from any of my physicians recently included an AI account of my entire visit. That made it so much easier to remember what was said in his office and how he suggested I proceed when I get home. It was a much easier way to digest all of the new information I received.

Great listener, empathetic, and thorough. I highly recommend this doctor!
