    It was my initial appointment with Dr. Ladenson. Prior to the appointment, I sent all my medical documents by fax as well as via MyChart Message. Dr. Ladenson must have been read all the documents I sent in advance as I didn't have to explain all the data. I appreciate his thoroughness and we had a productive conversation within the limited 40min visit. He had prepared the recommendation for my future treatment and he was very professional and personable.
