EXCELLENT Based on 706 reviews Posted on Google Stephanie WingTrustindex verifies that the original source of the review is Google. SO very thankful to have found Dr. Asgari, but LOVE his other attending doctor even more. I forgot his name, but WOW, he was fabulous. Took time to look me in the eye and really listen to me. He explained everything that my IBS D was doing to me, first time ANY of the many doctors I had been never explained it to me, and NOW I understand about the attacks, pain and restrictions perfectly now. He even helped me with my anxiety attacks.Posted on Google Tetyana DesignsTrustindex verifies that the original source of the review is Google. Very professional doctor and the staff!
