    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.

    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.
