    This was the best doctor I have ever seen. He spent more than enough time with me and seemed genuinely concerned about my health. Unlike many doctors who seem to talk a lot to demonstrate their competence, Doctor Hamrahian listened to my explanation of my health. He even sent a follow-up message after hours with an explanation of my test results and a recommendation for further tests and prescriptions.

He is knowledgeable, detail-oriented, and leaves ""no stone unturned"" in his diagnostic endeavor.
