Dr. Heydari is one of the kindest and intelligent doctors I have ever worked with in my life. Anytime I call with a concern, I am able to get an appointment within a day or two. while discussing my health, he talks in human language, which is completely understood, aside from some doctors who uses medical jargon. Dr. Heydari on the procedure he is going to do, but invests his time in the person you are. Other doctors could learn a lot from Dr. Heydari's bedside manner.
